SOLVED: The Case of the Unknown Bigamist
In a previous post talked about E’s husband the unknown bigamist, and I am pleased to announce that this bigamist is now known. This presents a unique opportunity for me to share how to find unknown grandparents using DNA, especially when traditional genealogy methods (like locating a marriage certificate) have not been successful. E’s grandchild…

Is this normal?
One of the interesting things that people have discovered as a result of DNA testing is family secrets that would have otherwise been taken to someone’s grave are being brought to light. Some people have discovered that who they thought was their biological parent was not, others have discovered half-siblings they never knew about. Occasionally…

What is a cousin?
One of my favourite things about being a genealogist is discovering new cousins. I have a lot of cousins now, some very distant, some a little closer. I have emailed back and forth with some, friended some on Facebook and even talked to some on the phone. It’s been really wonderful making all these connections.…

Triangulation, Part 4: Pileups
As I mentioned in this post, I have a funny problem on Chromosome 10. I have been working on this particular segment on this chromosome for a long time now. Here you can see the green of my great-aunt, and the other colours interrupting it. I’m guessing a piece of my grandma’s DNA inserted itself…

Triangulation, Part 3
I have been thinking a lot about triangulation since MyHeritage upgraded their chromosome browser (you can read about that here). People have been posting about their experiences using it in some of the genealogy Facebook groups I’m a part of. The first thing I realized is that many people don’t understand triangulation (heck, I didn’t…

Painting your matches with RootsFinder
I’m having a lot of fun exploring with Rootsfinder, but I’m waiting for when I’ve got more time and it’s got more updates (I’d really like a search function in the cluster graph) to really get into it. Since the experimental DNA tool is rather new, I’d like to explain a little bit about one…

Always Follow the Evidence
My uncle once told me that when you assume things, you make an ass/u/me. In the genealogy world, evidence is everything. And yet, being human, we like to draw conclusions based on the limited evidence we have. Sometimes our hunches can be right, and can draw us to find the evidence that confirms our hunch,…

Endogamy and RootsFinder
I started using RootsFinder because someone on one of the genetic genealogy Facebook groups I’m a part of posted a link to a blog post about the new experimental DNA tool. I watched the video and I was enthralled. I loved how it would paint everything for you once you identified how your matches were related to you.…

Triangulation, Part 2
I was asking about triangulation in the Genetic Genealogy Tips and Techniques Facebook group and I was fortunate enough to have Blaine Bettinger of The Genetic Genealogist answer my question. I’m pretty sure this is the equivalent of having Mozart answer your question about scales, and it’s probably not the first time he’s had to…
