Can DNA prove your hypothesis?
 
I love using DNA to help my genealogy! But let’s talk about how (autosomal) DNA works when I’m trying to find/prove the parents of a brick wall ancestor.

Giving Thanks (DNA Painter)

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.

Triangulation with GEDmatch

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.

For participants open to dipping their toes into Advanced territory, we’ll talk a bit about * triangulation *.

Chromosome Mapping with siblings – part 1

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.
