For whatever reason, I got my invitation to participate in the new Ancestry DNA program early, and I sent my sample back the day I got the kit. That’s where “pretty quick” stops.
I’ve watched too much television and retained some illusion that my results would be back within 46 minutes. They took a couple of months. My results contained no grenades: 64% British Isles, 32% Central European, and 4% Who the Heck Knows. That’s consistent with everything that I know of or have heard about my immigrant ancestors
Now I’m waiting for someone closer than my 29 probable 4th cousins to submit DNA samples. Nothing wrong with 4th cousins, and, yes, they may have research on families I’m looking at. Actually, and upon further reflection, I’m nor really sure what I’m waiting for; maybe for my brother or one of my sisters to say “Hey, Sibling!.” Maybe they won’t. We’ll see.
