In the United States, we celebrate a day of thanks every November. So, this month’s post deals with something I am thankful for in the genetic genealogy community. There are SO MANY people here who deserve our gratitude: citizen scientists, search angels who help adoptees, folks who answer newbies’ questions on social media, kin who graciously agree to take a DNA test… it was hard to pick one.
In the end, I decided to write my thanks to someone who has recently developed and shared an amazing (and free!) new DNA tool: Jonny Perl and his DNA Painter.
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!
“The best laid schemes o’ mice an’ men / Gang aft agley”, as the poet [Robert Burns] says.
In other words, herein lies what worked in my project to identify a good cM threshold for “false positives”… and what didn’t.
This month – another post on testing siblings and on using GEDmatch.
Sometimes, having siblings’ DNA tested is a real treat—such as when one of them connects to a distant cousin still residing in Ireland, just a few kilometers from where my ancestors came from. But sometimes—playing with sibling DNA can be a real challenge! Case in point: Chromosome mapping with three siblings. This is advanced stuff, yo.
Who were the parents of Benjamin Gorsuch, who died in Tuscarawas County, Ohio, in 1851?
I’m still looking for documentary evidence to identify them. But maybe DNA evidence will uncover some new leads too!
