Hello Mary.... I just saw your query about Zachariah Compton on Genforum (#8928) I believe that all of your data quoted is reliable.
As a further note, Zachariah Compton has been accepted as a soldier of the Virginia Militia in the Revolution... and any member of the fair sex proving direct relationship can secure membership in the DAR..(Go to DAR Records.)
It has been more or less accepted that he married Mary Middleton.. Some claim (Proof?) that Mary (Ann) Middleton was the daughter of James Middleton (the son of Robert Middleton) (q.v... Middleton Genealogy) I am sure that many are working on the sources of proof of the Mary Middleton relationship... Zachariah Compton was born in Maryland and died apparently in Flint Ridge, Culpeper County, Virginia..
If more information is needed, please contact me..
