For those of you interested in DNA testing to determine lineage, I recommend to you some past issues of Family Chronicle, a magazine devoted to genealogists. I feel fairly certain you can purchase past issues. However, check their webpage by using www.google.com and typing in family chronicle. There have been several articles by physician/researchers/scientists treating of this matter. I am NOT interested myself, as my maiden name was Williams!!! And, how many messed up Williams genealogies are in print and on the internet. E.W.Wallace
