Re: Abraham Burgess & Semantha Cheney
This family was descended from a Hessian (German) mercenary soldier who fought for the British in the Revolutionary War, and then decided to remain in the United States as the new country was launched (a not uncommon outcome). I have one partial DNA sample for this family in the Burgess DNA Project, which I captured from another website--but as one might expect, it presently doesn't match any others in the project. This family is NOT related to the other Burgess line in early Washington County--they were descended from Thomas Burgess of Barnstable Co., Mass., something that's also been confirmed genetically.
