Does anyone on this list have an all male line connecting to the subject Colby Jackson? If so, would you be interested in participating in the Jackson DNA tests? Colby Jackson was born about 1765, in either NC or VA, and served in the Revolutionary War with NC units. About 1810 or so, he and his family moved to what is now Madison County, AL and he died there about the late 1820s. Robert Nicholson
