Hi.
If you are interested in a DNA project to prove "Brassil relatedness", please contact me. I am in the process of proving the genetic relationship between 3 different Brassil lines already.
As my family name was spelled "Brazill" in Griffiths, please don't assume that these groups can't be related. In Fact, there are Newfoundland Brazils that I am 99.97% sure are related to me. It goes back to about 1775 though so the paper work just isn't there. That is where science will come in handy!
