Thanks, Maggie. I'm approaching halfway through that article and I haven't even tested my DNA with Ancestry yet! Very useful, though. I'm hoping that when I do get around to it I might have a clue where to start.
I was watching a video yesterday that covers some of the same ground. He comes to ThruLines just before minute 22.
New Tools at Ancestry DNA
I'll leave it to someone with hands-on experience to say how useful the video is, and I apologize in advance to any who want to strangle him the next time he utters the word "okay?"
EDIT:
Aha. I no sooner went back to reading your article than I found the name of Blaine Bettinger in the next paragraph or two. He is the author and narrator of the video I posted.
