AncestryDNA Genetic Communities went live this week! What does that mean for my genealogy? (And scroll to the end for something free that expires April 6 2017!)
On 25 Mar 2017, the Central Indiana DNA Interest Group is giving an in-depth presentation on the valuable (and mostly free!) DNA tools at GEDmatch.
At this program, we’ll be talking about the benefits of GEDmatch and walking through how to use the site. Of course, the most Basic perk of GEDmatch is that you can compare DNA from people who tested across different platforms (companies). On an Intermediate level, GEDmatch has tools to help you sort your matches into different lines of your family tree. For participants open to dipping their toes into Advanced territory, we’ll talk a bit about * triangulation *.
I know when I attend webinars or presentations, sometimes my brain gets full and doesn’t process everything I just heard. Then it’s helpful to have a resource to revisit later to help the more complex material sink in. So I thought I’d post something about * triangulation * on my blog this month!
What if your analysis of your match doesn’t match the shared cM chart?
Most people are able to find their Most Recent Common Ancestor (MRCA) when they share over 90 cM of matching DNA. Below that, it begins to get a little more challenging. In this February 2017 series of blog posts, I’ve been focusing on identifying the MRCA with people who share more than 60 cM with us, projected to be 4th cousins or closer. You may not have much in that range and have chosen to work with matches who share 45-60 cM with you. That’s okay. There are a few key reasons why we want to focus on this group.
The previous post in this short series talked about the genealogy basics one should have covered before dabbling in DNA. Now we’re ready to explore how to use some of the DNA information in conjunction with that genealogy.
Last month I suggested that soon I’d be sharing some results of a citizen science DNA project I’m working on. However, I realize now that the proposed blog draft is too long, with too many diversions to explain some basics that might help newer readers.
So I’m taking a step back and planning several short posts first. The theme is ‘Using shared cM counts to help find the common ancestor.’
Starting off the new year with a new citizen.science post!
Has it ever crossed your mind that part of genetic genealogy is a little bit like The Big Bang Theory?
December—it’s a good time to reflect on the year’s accomplishments and on goals for the new year. Right? Here are mine, related to genetic genealogy.
