... Annual International Conference on Genetic Genealogy held each year by Family Tree DNA and I’ll be going to Houston from November 10 to 12 to attend.

GCGS 2017 Day 3 - Blog entry by lkessler - 15 Oct 2017
... breakfast together, and then I led off repeating my talk from the day before on intro DNA. I had a few less people than the day before since many had already been at my first talk.

Triangulation does NOT mean IBD - Blog comment by debbiek - 4 Oct 2017
