Welcome! We meet the second Tuesday of most months at the LDS Church on Monument Avenue. Come join us!

May 12, 2020 Meeting: The Women Who Contributed to Our DNA

Continuing the Mother’s Day celebration, we’ll be talking about using DNA to explore the women in our family, including autosomal DNA, mitochondrial DNA, and X-DNA.

April 14, 2020 Meeting: DNA To-Do List items you can do at home!

In keeping with stay at home recommendations, the April meeting will be held ONLINE! If you subscribe to the GRIVA email newsletter, watch for an upcoming email with registration information.

We’ll offer some things you can do while you’re stuck at home. See you then!

March 10, 2020 Meeting: Collaboration

We talked about collaboration. From working trees, evaluating our shared matches, contacting matches, and target testing relatives, there are many ways to collaborate with people.

See https://www.legacytree.com/blog/13-secrets-to-getting-replies-from-dna-cousin-matches for some great tips for contacting matches. And, if you have a subscription to Family Tree Webinars, Blaine Bettinger has a webinar in their library, titled “Begging for Spit” that we highly recommend.

February 11, 2020 Meeting: Tools

We talked about tools to help us in analyzing and organizing our DNA test results. First, we talked about tools at the testing company websites, such as Ancestry’s ThruLines and Common Ancestor hints or MyHeritage’s Theories of Family Relativity. Some of the third party tools we discussed included:

September 10 Meeting: An Introduction To Using Chromosome Browsers

This month, we’ll be talking about chromosome browsers and DNA segments and how we can use them to help with our genealogy.

DAYTIME DNA SIG Meetings: July 29, August 12, and August 19!

To accommodate those interested in attending the DNA meetings but unable to attend Tuesday evenings, we’re going to hold a few daytime DNA SIG meetings! They will be at NOON at the John Rolfe Commons Publix.

Enter Publix through the door opposite the YMCA end of the store. Grab some lunch (hot bar, cold bar, deli, etc) then wind your way around to the right and find the elevator or take the steps up to the community room. Enjoy your lunch and friends. The program will start around 12:30. See you there!

June 11 Meeting: Tips & Techniques for Working with Ancestry DNA Matches

At our next meeting, we’ll be discussing AncestryDNA. It will be part review, part catching us up to the newest features, and some tips for working with matches who have no trees, or small trees, or private trees. See you there, 7:00pm at the LDS Church on Monument Avenue!

GEDMatch News

GEDmatch Genesis and GEDmatch Legacy have now merged into one site, accessible at https://www.gedmatch.com. No more confusion about two sites – there’s only the one, with all of the capabilities we’ve been getting used to at Genesis.

In addition to the merge, GEDmatch has now changed how your kit is accessible to law enforcement. For the past year, everyone who uploaded a kit to GEDmatch and made it public would have their DNA available to law enforcement agencies looking to solve cold cases. Now, they’ve opted everyone out of law enforcement matching (but still available to fellow genealogists!). You can opt your kit(s) in to law enforcement matching if you want your DNA to be available to law enforcement, or do nothing if you do not want your DNA used in this way. You’ll see more information as you log in to GEDmatch.

May 14 Meeting: Using Multiple DNA Testing Companies

Thanks to everyone who joined us in May! We talked about using clues from matches at more than one company to solve a puzzle, pulling together some of what we’ve learned earlier in the year.

April 25 is DNA Day!

April 25 commemorates the announcement of the discovery of DNA. The DNA companies typically celebrate by having sales and promotions, so watch the web pages for AncestryDNA, 23andMe, Family Tree DNA, MyHeritage, and Living DNA on the 25th.

Sometimes, the sale prices are honored at Amazon.com. If you purchase DNA kits (or anything else) from Amazon, please consider using GRIVA’s Amazon Smile link. Simply click the link first, then eligible purchases at Amazon will benefit GRIVA, at no additional cost to you! The link is:

April 9 Meeting: Clustering our DNA Matches

Thanks to everyone who came to the April 9 DNA SIG meeting! We had fun talking about the different methods and tools for DNA match clustering!

Here are some blog posts and videos explaining and demonstrating some of the ways of clustering. The tools are essentially doing the same thing – grouping our matches, often visually, to help us see patterns that we might not see in a list of names. Just in preparing for this lecture, I found a cluster of people I have no idea how I match, and that cluster may hold the answers to some brick walls.

March 12 Meeting – New Features from AncestryDNA and MyHeritage

Thanks to everyone who came to the March 12 DNA SIG meeting! We had fun talking about the new features at AncestryDNA and at MyHeritage.
Here are some blog posts and some videos with more information about the new features.
And, as I said multiple times during the presentation, and as Blaine says multiple times in his videos and lectures, tools are great at creating hypotheses, but they are NOT producing ready-made conclusions. It is up to us to research and verify what we find in any tool or any record. Here’s a blog post from Judy Russell on that: https://www.legalgenealogist.com/2019/03/03/no-magic-wands/
