The previous post lists a James Harvey Alexander b abt 1810.
The Alexander DNA Project has a new member who traces himself back to (but no further than) James Harvey Alexander (1810 -?) born in Ky; Living in Illinois in 1870.
When we get his DNA results it will show if the James b abt 1754, husband of Mary Sample and a son of a William is related.Because that James b abt 1754 we believe descends from the 7 brothers and 2 sisters of Cecil Co. MD fame, and we have about 30 members from that line.
I would love to hear back from J. F. Alexander on this subject.
