I4GG 2020 round up

Feb7

My favorite yearly conference is the two days of talks that i4GG puts together for us serious genetic genealogists. Thank you CeCe and Lennart for doing this and for making the very professional videos, which are free to conference attendees and available for purchase by everyone else.

One of the highlights of the conference was hearing from Paul Fronczak and his daughter. Paul was the child returned to his parents after the famous Chicago baby-napping case in 1964. In 2012 a DNA test showed that he was not their child. His book The Foundling, about his search for his roots, his missing twin sister, and the real Paul Fronczak, is a terrific read. (click here for the BBC summary of the case)

I have just started using a great tool called Scapple, that I learned about from Michelle Trostler‘s talk. So far I love it! It is an inexpensive mind mapping package that makes it super easy to quickly put together possible family charts for clients. It is always pleasurable to hear about actual cases and how they were solved. Both Michelle and Carol Rolnick obliged.

Chaos ensued when Katherine Borges, the director of ISOGG (whose Wiki is my go to resource), told us about the FamilySearch app with “Relatives Around Me” on its menu towards the end of her epigenetics talk. Everyone was downloading it to their smartphones and running around finding their cousins. I discovered many 12th cousins, including Tim Janzen, from a dubious connection that needs more research, a Thomas Gray who went to Norway and became Graa. Sadly I never did find my real 8th cousin Dixie Hansen in the room!

I presented on What’s New at GEDmatch and also about Automated Tree Building Tools, focusing on DNA2tree, as Dana Leeds was covering Genetic Affairs (GA) which she did quite well. I do have a blog post on GA in progress, it now includes GEDCOMs with the tree building! As always my slides can be found at https://slides.com/kittycooper


The biggest take away from the conference for me was that we all need to be more diligent in getting our relatives to opt in to law enforcement (LE) usage on GEDmatch. Many of the cases that have been solved with genetic genealogy could not be done today now that the usable database for LE investigations is down to about 200K from over a million before the opt in requirement.

Also perhaps we need a team to identify kits of people who are deceased. GEDmatch will opt them in if presented with an obituary.

I am also putting together a new email message to send to reluctant cousins appealing to their desire to be good citizens.

How to Share Ancestry DNA Results

Jan29

Sharing DNA results at Ancestry.com is very useful when you want to see how much your relative shares with other relatives. All that this sharing allows you is the ability to see their match list, their ThruLines, and their ethnicity results, not their raw DNA nor the ability to download it.

Being able to see a cousin’s ethnicity may help figure out which side of the family that Finnish DNA is from or whatever puzzling ancestry you are interested in. Seeing their match list can be extremely useful for solving a mystery or just for the fun process of collecting family data.

For years I have been referring my cousins to an old blog post kindly written by genetic genealogist Angie Bush which explained how to initiate a share. However by now the screen shots are long out of date, so here is a new step by step for this process created by sharing my results with my brother.

1. Go to your DNA home page by clicking on Your DNA Results Summary in the drop down menu under DNA in the top menu (see my pink arrow)

2. Click on Settings at the top right of the page (another pink arrow)

Upcoming talks, i4GG, and a case solved using the latest DNA tools

Jan10

Unknown parentage searches have changed dramatically over the last year thanks to a number of great new automated tools. I will be updating my presentation on this for the upcoming i4GG conference in Las Vegas in a few weeks, the first weekend in February. I will also probably talk about what’s new at GEDmatch as well as be on a panel there.

Plus I will present how to use these new wonderful tools to explore your cousin matches at the North County DIG meeting next Saturday, January 18.

Below is a screen shot of the final slide in my unknown parentage presentation where I list the steps, in order, that I currently go through on these searches. I need to add at the beginning another step, “check the ethnicity,” as it can be a huge clue when the two parents are descended from very different populations. Click here for a recent blog post on a case solved with ethnicity. Also I have found that the listed communities at Ancestry are pretty accurate so they can be quite useful too.

Finding an unknown father in a few hours with DNA has become much more common due to the large number of American testers. A neighbor, let’s call her Dede, noticed I was a genealogist on FaceBook, so contacted me for help late one evening in December. She asked if I could help figure out who her unknown Dad was from her DNA results. She was a bit discouraged because no one had answered her messages.

Dede was tested on Ancestry and although her mother was not tested, a known maternal first cousin happened to be in her match list. That would be useful for separating the maternal from the paternal matches. Dede’s ethnicity had a surprisingly high 47% German percentage while her first cousin had only 27% . Plus that cousin had no Eastern Europe (Dede 10%) or Baltic (Dede 3%) so perhaps Dede’s father was part Germanic and Slavic.

Dede’s ethnicity at Ancestry  – note the Kentucky community

I took a quick look at her Ancestry match list and saw several paternal 2nd and 3rd cousin matches so I told her that it would be pretty easy, then quoted her my discount rates and a estimate. The next day I sent her the wedding picture of her father’s parents. She and her family drove to Oregon after Christmas to get to know her half sister and Dad. What a magical Holiday it was for all!

Great New DNA Tools in 2019

Dec31

2019 was a great year for DNA. Many wonderful DNA tools were created by the testing companies as well as by a number of third parties. Throughout this article I will list my blog posts which discuss the tools from 2019.

I have found so many new cousins thanks to ThruLines at Ancestry plus the deployment of that to my DNA matches. My current process is to sort my matches by date and then filter for just 4th cousins or better (or 15cm or better) to catch new matches while they are still logging in and so might see my messages. Also once a week I check my matches that have common ancestors to see if any new ones have been connected in (since I note how people are related in the notes, anyone with blank notes is someone I have not yet seen the tree connection for):

MyHeritage‘s Theory of Family Relativity also makes it easier to find new cousins. Many of my Norwegian cousins have been found there. I even got a message from one this morning!

23andme may be finally trying to consider us genealogists. They added a build your tree from DNA feature (yet to be blogged about here) and connected to the FamilySearch tree. My wish for 2020 is that they combine those features!

My favorite new 3rd party tools in 2019 are DNA2tree, a game changer for unknown parentage cases, and the addition of trees to the automated clustering at Genetic affairs. I confess, I actually bought myself an iPad so I could use DNA2tree.

Automated clustering really took off in 2019 with GEDmatch, DNAgedcom, and MyHeritage all adding clustering.

2019 also saw the birth of a new public database for Y and mitochondrial results at https://www.mitoydna.org/ (to be reviewed soon).

I have yet to cover all the great new tools at DNApainter.com although I refer people to the online relationship calculator there regularly.

Other new tools sites that I need to review are Borland genetics tools and Your DNA Family

2019 has been a really great year for DNA tools!

Important Changes at GEDmatch

Dec17

If you have not logged into GEDmatch recently, please do so and either accept the new terms and conditions or don’t. Unless you are clearly USA based*, your kits will not be visible to your relatives any more unless you accept. I have linked to numerous other blogs at the end of this article to help you make your choice. I recommend reading either the one from Roberta Estes or EU users, the one from Debbie Kennett. Both look carefully at the new terms and conditions which are not very different from before.

Frankly, I was surprised by the panic expressed last week by some in the genetic genealogy world on FaceBook due to the sale of our beloved GEDmatch DNA tools site to a forensic science company. Personally, I hate knee jerk reactions so I did some research into this company, Verogen, as well as communicated extensively with Curtis Rodgers, one of the GEDmatch founders, and Kim Mohr, a spokesperson for Verogen.

To remind you all, GEDmatch is the best place to compare DNA tests done at different companies to each other or just to see the actual chromosome locations shared by two Ancestry testers. While both Family Tree DNA (ftDNA) and MyHeritage accept uploads of tests from other companies so you can compare on those sites, neither has the extensive tools of GEDmatch. FtDNA compares down to very small segments which can be useful in a family project but leads to inaccurate relationship estimates. MyHeritage does not show the X chromosome and neither company shows the fully identical segments (FIRs) that full siblings will have, which can be so helpful (click here).

The DNA Applications menu at GEDmatch

GEDmatch has many useful additional tools, such as “People who match both or 1 of 2 kits ,” an “Are your parents related?” test, the ability to see who matches you on a specific segment, being able to check for full siblings rather than half, and automated triangulation, to name a few of my favorites (click those words to go to that post when I did one or click here for my more general GEDmatch articles). Plus it has GEDCOM comparison utilities. Compare yours to all the ones in the database or to just one other.

GEDmatch became a center of controversy when it was discovered that genetic genealogist Barbara Rae-Venter, working with law enforcement (LE). had solved the Golden State Killer case (click here) using that site. Since that time, there have been more controversies around law enforcement’s use of the site and many overblown scare articles in the press. Personally if my DNA outs a distant cousin who is a murderer or rapist, that’s fine with me. Genetic genealogy techniques are used as a tip; no one is arrested without getting their DNA from discarded materials and seeing if it is a match to the crime scene. I know some people are afraid of the possibility of false arrests, but that just does not happen with these modern techniques. You can, as before, choose to opt out of allowing LE to see your results on GEDmatch when looking for cousin matches to the dna of the perp or the unidentified victim.

In recent months, there have been more problems, news stories and controversies, including a Florida search warrant being granted. One has to feel for the two retired hobbyists who founded GEDmatch to help in their research and ultimately help us all, keeping most of the features free. Clearly getting the site owned and managed by a more professional group would be of great advantage to the users. Curtis spent several months looking for the right partner that would respect the original misson of GEDmatch and yet deal appropriately with LE, the EU, and security issues. He and the programmers, the two Johns, will continue to work on the site as consultants.

So who or what is Verogen? Two years ago this company was spun off from Illumina (the maker of the chips and machines that all the consumer oriented DNA testing companies use to sequence your DNA). It has 50 plus employees and plans to continue growing. Their office is in a small office park near UCSD here in San Diego. Continue reading →
