The Russian genetic genealogy community is actually quite vibrant. Lots of scientific and hobbyist research, and several Russian forums (sometimes even in English :)) and websites with Y-DNA tools.

Results for individual SNPs seem to come in a lot sooner than the estimated completion date. I doubt you'll even have to wait half that time.

I'd hold off on ordering any autosomal tests from Ancestry. Their record on DNA testing has been pretty bad, and they aren't letting people who've tested download their own raw data. I had my sister...

Their haplogroup assignments are probably accurate, but limited to the SNPs that are "hardwired" onto their chips; plus they're using an even more outdated haplotree than FTDNA. The important...
