Yes I have, and a number of my relatives. I think it is pretty damned accurate, and it has linked me up with family I was not aware of and nailed my heritage as far as Im concerned. Worth the price and it provides really interesting information.
Used Ancestry dna.
It is still on sale but you missed the 50% off that ended a few days ago. Buy it on Amazon, it gets to you in a day or two, thru Ancestry it takes a few weeks.
