DNA

Where Are the "Holes" In My Pedigree Chart? Can DNA Help?

While wading through my Genetic Affairs AutoCluster results for AncestryDNA (seMy Last AncestryDNA AutoCluster AutoTree Analysis From Genetic Affairs – Post 1), I noted that I have many DNA match clusters that don’t have a known common ancestor, based on my Notes for each DNA Match.  For instance cluster #1 has 26 entries, but no known common ancestor.  I’m pretty sure that the common ancestor for that cluster is on my father’s Seaver side of the family, but none of those matches has an Ancestry Member Tree that includes one of my Seaver line ancestors back up to the 5th great-grandparents.

I have about 400 AncestryDNA ThruLines that define Common Ancestors for me based on my tree, DNA match trees, and the Ancestry Big Tree.  These are very helpful, but are not always accurate (my estimate is that about 5% of my ThruLines are incorrect).  

There are more Common Ancestors identified with ThruLines than by Genetic Affairs because of the methodology used by each analysis (Genetic Affairs uses only my tree and a DNA Match’s tree, not the Ancestry Big Tree).

How can I figure out who might be the Common Ancestor for more of my DNA Matches, especially in clusters?  The first step should be to define what I think I know and what I don’t know about my ancestry.  Here is a 7-generation chart from the FamilySearch Family Tree (out to 4th great-grandparents).  I wish I could make an 8-generation chart to get to 5th great-grandparents!


My unknown ancestors on this chart are:

*  4th great-grandparents, parents of John Richman (1789-1867).

*  4th great-grandparents, parents of Ann Marshman (1784-1856).  The chart shows parents that I think are incorrect.

*  4th great-grandparents, parents of John Rich (1790-1868).  The chart shows parents that I think are incorrect.

*  4th great-grandmother, mother of Sarah Feather and wife of Cornelius Feather.  The chart above calls her Mrs. Cornelius Feather.

*  3rd great-grandparent, a parent of Devier J. Lamphier Smith (1839-1894).  Devier was adopted as an infant, and I’m pretty sure one set of his grandparents are Isaac and Rosanna (Laun) Lanfear (based on DNA matches), but the other parent (male? female?) is a mystery.

*  4th great-grandparents, parents of William Knapp (1775-1856).  Ancestry offers potential ancestors that I am sure are incorrect.

*  4th great-grandparents, parents of Sarah Fletcher (1802-1850).  

I have other “holes” in the 5th great-grandparents not shown on the chart above that may be the Common Ancestors of some of the Genetic Affairs clusters.  

My next step in this analysis process is to identify my AncestryDNA Common Ancestors on the fan chart to see which of my known ancestors don’t have any matches, and which clusters might account for one or more of my “holes” in my fan chart.

Ancestry Launches New Genetic Communities

North American Genetic Communities map from AncestryDNAAncestry launched Genetic Communities last week. “Think of the AncestryDNA ethnicity estimates on steroids, and you’ll have a sense of what this is,” Tim Sullivan told RootsTech attendees last February. While ethnicity estimates show your genetic origins from hundreds to thousands of years ago, the Genetic Communities feature shows groups of people you are related to in the last few hundred years. Ancestry defines a Genetic Community as “a group of people who are connected to each other through DNA, most likely because they share a common history or lived in the same places.”

Kendall Hulet said, “Applying rigorous statistics and scientific development, we’ve created a unique experience that can connect you through your DNA to places your ancestors called home and the migration paths they followed to get there.” This doesn’t necessarily pin your particular ancestors to a particular place, since your ancestor may have been an outlier. Chances are good, however, that Ancestry will nail part of your ancestry to a particular region and timeframe.

AncestryDNA has identified over 300 communities with plans to release more in the future. Brad Argent of AncestryUK says that most people are members of at least one Genetic Community, some people are members of two, and, rarely, some are members of three. In my case, I am a member of one.

My ethnicity map now shows my ethnicity estimates on a dark azure map. (Can I just say, I don’t like this new color scheme?) Notice that Ancestry has narrowed (not!) my Native American ancestry to the entire Western hemisphere. Not very helpful in determining my tribal origin (Massachuset).

But notice the small Orange spot on Utah? That’s my genetic community, “Mormon Pioneers in the Mountain West.”

While my genetic community is of no surprise to me (I’m 5th generation Mormon on every single line—my ancestors all being good genealogists—I was born into a completely full, 7-generation pedigree), a Genetic Community could be very interesting to someone vaguely aware of—say—Germanic roots.

Your Genetic Communities are listed beneath your ethnicity pie chart on the left side of the page. The way statistics work, AncestryDNA can’t say with 100% confidence that you are a member of a community.

When you click on your community, you are given an overview of the community.

Scrolling past the overview reveals migration time periods with commentary.

Selecting a time period shows a migration map, different for each time period. Orange dots show birthplaces from community members’ Ancestry Trees during that time period. Pins show birthplaces from your own tree. Animated lines show the direction of migration.

Did you notice, I’m aboot one-fourth Canadian, eh?

Beneath the community name, two buttons select between the default Story view, which I’ve shown above, and Connection view. Connection view states that they are 95% confident that I am a member of the Mormon Pioneers Genetic Community, and that it has 89,000 members. Connection view provides a link to see all 737 of the ones that I am related to. It also lists common surnames in the community:

Last names associated with my genetic community

Hmmm. Anything jump out at you?

To see Genetic Communities, you don’t need to have a tree or a paid Ancestry subscription. It is available for free to everyone who has had an AncestryDNA test.

Monday Genea-Pourri – Week Ending 25 May 2020

Here are the highlights of my family history and genealogy related activities over the past week:

1)  Moderated and hosted the Chula Vista Genealogical Society DNA Interest Group meeting on Wednesday, 20 May in a Zoom meeting, with 12 in attendance.  I discussed the new AncestryDNA Tree icons and the changed DNA Match screen with a ThruLine; the MyHeritageDNA Theory of Family Relativity update, along with how I write Notes and use the chromosome browser; the CeCe Moore TV show on 26 May; ethnicity estimates and communicating with AncestryDNA matches.  In the second hour, the attendees discussed their challenges and successes.

2)  Participated in the San Diego Genelaogical Society DNA Interest Group Zoom meeting on Saturday, 23 May.  Colin made two presentations – an Overview of recent DNA features, and on GEDmatch.
3)  Participated in today’s Mondays With Myrt on Zoom.  We learned how to set up the Closed Captioning using Streamer and tested it out.  

4)  Watched the Family Tree Webinar Fridays in May: Your Questions Answered LIVE—More DNA with Diahan” by Diahan Southard.

5)  Wrote and posted a biographical sketch of 7th great-grandfather #542 George Stearns  (1688-1760) for my 52 Ancestors biographical sketch on Friday.  

6)  Transcribed the 1783 Will of Nathan Brigham (1693-1784) of Southborough, Mass. for Amanuensis Monday.  

7)  Continued sorting out the Seaver families in Philadelphia in the 1850-1900 time frame.  Wrote a series of blog posts about some of them.  Added events and sources to many of them with Ancestry Hints.

8)  Added Notes to about 26 more AncestryDNA matches with cM values, relationships and known common ancestors.  Added one AncestryDNA ThruLine to the RootsMagic family tree database.  Reviewed new DNA matches on AncestryDNA, MyHeritageDNA, FamilyTreeDNA and 23andMe.  

9) There were several sessions working in the RootsMagic software program to match with and update FamilySearch Family Tree profiles for Seaver families and my ancestral families, with occasional additions to the RootsMagic profiles. I have matched 35,807 of my RootsMagic persons with FamilySearch Family Tree profiles (up 134).

10)  Used Web Hints and Record Matches from Ancestry, MyHeritage, Findmypast and FamilySearch to add content and sources to my RootsMagic profiles.  I now have 57,656 persons in my RootsMagic file (up 148) , and 121,180 source citations (up 579).   I TreeShared with my Ancestry Member Tree two times this week updating 341 profiles, and I resolved 881 Ancestry Hints.  I’ve fallen behind on the Ancestry Record Hints with 131,309 to be resolved, but I work on them almost daily.    

11)  Updated my presentation on “Using Collaborative ‘BIG’ Family Trees” for the CVGS program on Wednesday in a Zoom meeting.

12)  Wrote 20 Genea-Musings blog posts last week, of which two were a press release.  The most popular post last week was Did Sarah Giberson Marry Two Seaver Men? – Part I with over 458 views.  

13)  We are still fine here at the Genea-cave, hunkered down and not going out much.  I went to the grocery store on Tuesday and Friday and it wasn’t too busy.  I picked some weeds and am still thinking about mowing the back yard again.  I pushed Linda in the wheelchair up and down the block on Sunday.We watched the church choir and pastor’s sermon on YouTube on Sunday.  Other than that, it was stay-at-home on the computer doing genealogy, eating and sleeping, plus reading ebooks on my laptop while watching TV.

Erroneous AncestryDNA Genetic Community

North American Genetic Communities map from AncestryDNAReader Clytee Gold wrote me about an apparently erroneous AncestryDNA Genetic Community assignment. One of her two communities is “Mormon Pioneers in the West.” (First, I am jealous that she has two community assignments.) She is rather positive that none of her ancestors were ever Mormons. She has done extensive research and has never found any connection to the Church. As there are still pockets of prejudice against members of The Church of Jesus Christ of Latter-day Saints, this assignment could be highly offensive to some people. Coincidentally—or not—it is not offensive to Clytee. Forty years ago she joined the Church and moved to Utah. She is, literally, the “Mormon Pioneer in the West” of her family.

I’m not qualified to explain how this misassignment occurred, but fools rush in where angels fear to tread. Perhaps experts among my readers can correct me. Clytee gave one possible explanation:

The only thing I can figure out is that is based on OTHERS testing (guess that makes a community – who else took the test to compare to), and that somewhere, 5-6 generations back a sibling of a great-great something of mine joined the church in Denmark in the late 1800’s and came to Utah as a “Mormon Pioneer in the west” and populated the west and there are lots of descendants who took the DNA test.

Ancestry has explained that they use an algorithm called community detection to detect groups of individuals with a large number of interconnections. I think of it like large DNA Circles that don’t require common ancestors. The Mormon Pioneers community contains 89,000 testers. Just like a DNA Circle, Ancestry states a confidence level for your membership in the genetic community. My connection to the Mormon Pioneers community is “Very Likely.”

Ancestry says they then examine the Ancestry Member Trees of the genetic community “to learn about the historical forces that may have brought their ancestors together.” Of course, some testers don’t have trees, some don’t include all their ancestors, some have ancestors without complete location information, and some have complete garbage in their trees. I assume Ancestry looks for common locations in 25-year increments. If they find a large number of ancestors who lived in the same place at the same time, they look into the history of that time period and why there was a large number of individuals there. Then they give that community a name.

For example, the sweet spot for one genetic community is centered on Massachusetts in 1725-1750 (shown on the map, below left). Ancestry chose to name that community, “Settlers of Colonial New England.” Another centered on Utah at a much later time period, 1875-1900 (below, right). Ancestry called this one “Mormon Pioneers in the Mountain West.”

AncestryDNA genetic community map for Settlers of Colonial New England, 1725-1750. AncestryDNA genetic community map for Mormon Pioneers in the Mountain West, 1875-1900

I assume Ancestry can follow the group forward and backward in time, up and down the member trees. This provides additional touchpoints to compare against historical sources and decide if they have correctly identified and named the genetic communities. Moving forward in time gives an interesting view on migration that may not be available from other demographic sources. This may truly be groundbreaking demographic tools. For example, look at the 1900-1925 map (below) of the descendants of early residents of Chihuahua and Durango. If I am interpreting the map right, by that time they were as likely to be living in El Paso as Chihuahua. (The large circle over central Texas represents ancestors whose member trees didn’t specify where in Texas they lived.)

AncestryDNA genetic community map for early residents of Chihuahua and Durango, 1900-1925

Moving backwards in time gives an interesting view on where the Mormons who settled in Utah came from. In the period 1825-1850, most were living in England, with a fair number in Denmark. (See map, below.) The surnames associated with the Mormon pioneer genetic community further point to Denmark:

Jensen, Christensen, Larsen, Hansen, Allred, Nielsen, Olsen, Sorensen, Nielson, Rasmussen, Christiansen, Madsen, Peterson, Anderson, Barney, Leavitt, Child, Andersen, Petersen, and Jorgensen

AncestryDNA genetic community map for Mormon Pioneers in the Mountain West, 1825-1850

Once they are sure they have identified the genetic community, Ancestry can take information from history books about that group and display it next to the migration map. However, the information may not apply to your ancestors who didn’t participate in the chain migration. That is how Clytee may have been put in a migratory group that her ancestors didn’t participate in. She told me her ancestry:

My father was half Swiss (4 generations from the immigrant to Missouri) and half German (5 generations from the immigrant to Missouri).  Mother half Norwegian (2nd generation from the immigrant to Iowa) and half Danish (2nd generation from the immigrant to Iowa).

I think the conjunction on Denmark is more than coincidence. Clytee’s Danish ancestors didn’t have to join the Mormon church for her ancestors to share DNA with those that did. I don’t think it had to have been a sibling in genealogic-time, either. I think Ancestry is looking at shared DNA in a closed community with hundreds of years of intermarriages.

There is a possibility that the genetic community Ancestry has identified is actually more specific than “all Mormon pioneers.” Ancestry may have identified DNA of Mormon pioneers of Danish origin. Look back at the dominant surnames for this genetic community. Does it look more English or Danish?

There are other possibilities. Remember the mention of confidence level? Clytee may not belong to the genetic community at all. Her DNA may just be a statistical anomaly. Remember the mention of garbage trees? Ancestry may be running calculations overwhelmed by erroneous information.

GIGO. Garbage in—garbage out.

Thank you, Clytee, for your message.

Taal Volcano, Google One, Meena, More: Sunday ResearchBuzz, February 2, 2020

NEW RESOURCES

Good News Pilipinas: University of the Philippines opens portal on Taal Volcano data, 1st in Asia to offer public access. “The Taal Volcano LiDAR datasets were derived through the use of airborne systems mounted on an airplane. The output of the LiDAR sensor is a 3D point cloud containing points that were scanned. The LiDAR technology was able to generate maps with resolution of up to 1×1 meter which can be used for planning and reconstruction of areas damaged by the Taal Volcano eruption in Batangas on January 12, 2020. The Taal Volcano mapping is free and downloadable by anyone with internet access and by most modern GIS software.”

TWEAKS AND UPDATES

Android Police: Google is killing Google One Today, gives supporters only a week’s notice. “Today Google has announced that it’s killing its One Today service. This isn’t the renamed Google Drive paid storage program, but an app-based donation system you’ve probably never heard of, haven’t used, and won’t miss. Those still using it have a week before it shuts down.”

The Register: Google says its latest chatbot is the most human-like ever – trained on our species’ best works: 341GB of social media. “AI researchers at Google have trained a giant neural network using a whopping 341GB of discussions scraped from public social media to create what they believe is the most human-like chatbot ever.” Just read this story because the quoted conversation between Meena and a human is glorious. Why? Because it was outstanding in its field!

TechCrunch: Snapchat launches Bitmoji TV: zany 4-min cartoons of your avatar. “f you were the star of every show, would you watch more mobile television? Snapchat is betting that narcissism drives resonance for its new weekly videos that put you and your friends’ customizable Bitmoji avatars into a flurry of silly animated situations. Bitmoji TV premieres on Saturday morning, and it’s remarkably funny, exciting and addictive. Think cartoon SNL on fast-forward, with you playing a secret agent, a zombie president or a Moonlympics athlete.”

USEFUL STUFF

Search Engine Watch: The perils of tricking Google’s algorithm. “Google has been regularly introducing algorithm updates to improve the quality of its search results. But it also penalizes sites that employ unethical or outdated practices to rank higher. This can adversely impact a brand’s reputation and bottom line. Ideally, these updates should be used as a guide for improving a site’s UX, ranking on SERPs is an end result that will follow. Read on to know the ill-effects of chasing Google’s algorithms. There’s also a bonus involved! You will also learn some effective tips to stay on top of these updates while boosting your business reputation.”

AROUND THE SEARCH AND SOCIAL MEDIA WORLD

New York Times: Doctors on TikTok Try to Go Viral. “On TikTok, sex ed is being flipped on its head. Teenagers who load the app might find guidance set to the pulsing beat of ‘Sex Talk’ by Megan Thee Stallion. A doctor, sporting scrubs and grinning into her camera, instructs them on how to respond if a condom breaks during sex: The pill Plan B can be 95 percent effective, the video explains.”

Yale News: Collection of Musical Instruments to resume public hours. “Musette, Mayuri, Double Virginal. Yale students may have never heard of these instruments, but they reside only a step away at 15 Hillhouse Ave. The Romanesque building — which holds Yale’s Collection of Musical Instruments has been under renovation since May 2019 — will resume public hours starting the last week of February…. The collection is additionally expanding its online catalogue of instruments. Timothy Feil, who currently works at the collection, noted that the catalogue will provide information for visitors who want to know more about the showcased instruments.”

SECURITY & LEGAL

Neowin: YouTube Music’s restrictions on kids’ content leads to quirks with many Disney tracks. “Google found itself in trouble with the law last year due to YouTube’s and its own privacy policies pertaining to minors. The search giant was slapped with a multi-million dollar fine as it was found to be in violation of the Children’s Online Privacy Protection Act (COPPA). The company, however, began bringing a slew of changes to the platform ahead of the ruling, followed by official announcements later. As part of those changes and feature additions, the firm brought about certain restrictions on content that creators label as being made for kids. Those very changes, however, might be resulting in some annoying issues on YouTube Music for such content, especially for those from Disney Music.”

Techdirt: CBS Gets Angry Joe’s YouTube Review Of ‘Picard’ Taken Down For Using 26 Seconds Of The Show’s Trailer. “Joe Vargas, who makes the fantastic The Angry Joe Show on YouTube, isn’t a complete stranger to Techdirt’s pages. You may recall that this angry reviewer of all things pop culture swore off doing reviews of Nintendo products a while back after Nintendo prevented Vargas from monetizing a review of a a game…. CBS recently got Angry Joe’s YouTube review of ‘Picard’ taken down, claiming copyright on the 2 thirteen-second videos of the show’s publicly available trailer that Vargas used in the review.”

RESEARCH & OPINION

Mashable: Self-driving Waymo minivans will assist UPS with deliveries. “On Wednesday, Google spin-off company Waymo announced a partnership with UPS, the package delivery service. Soon, Waymo’s self-driving Chrysler Pacifica minivans will be moving packages around instead of humans.”

EurekAlert: DNA extracted in museum samples can reveal genetic secrets. “Researchers have used a vortex fluidic device (VFD) to speed up DNA extraction from an American lobster preserved in formaldehyde – with the results providing a roadmap for exploring DNA from millions of valuable and even extinct species in museums worldwide.”

9News Australia: World-first 3D map shows smoke plumes from Australian bushfires as captured from space. “In a world-first, an interactive map depicting the height of smoke plumes from bushfires during the peak of Australia’s bushfire crisis has been released. It is hoped that the new tool will improve the Bureau of Meteorology’s ability to predict where potentially dangerous smoke haze will move, as well as provide crucial ‘big picture’ information to disaster management agencies.” Good morning, Internet…
