Hi I do not know if this will help but i have a John Mason Hall b 1758 d. 1835 in Patrick Co. Virginia. I have no wife for this John or who his siblings might be. But I do have Some other information for him. Like who his father was..And he was Reverand Nathaniel Hall b.1738 Abington Parish, Glouchester Virginia (He is the only child i have for John Hall and Sarah Unknown but I just know there's More than one child). He married Ann Rowe.they had 9 children, #5 was John Mason and #8 was Jonthan b.1761 d. 1844 in Tennesse. I do not have any spouses for these two fella's but am assuming that one of the 5 or 6 John Hall's I have in my data base had another John Hall. My search has taken me back to 1640 Thomas Hall born in England he married Margery Claxon She was born in Virginia. My line from Thomas 1640 ,John 1664,John 1686,John 1722,Nathaniel 1738(I am missing all of his brother's and sister's),Nancy 1765 She married a Storm they had anna Francess storm who married a John whitman, they had William Bell Whitman he married lydia Watkins Adams and had Susan Francis Whitman who married a Heninger and three generations later here i am..Anyway if you run across these surnames it might hold some sort of information also. Also Try the Mid Atlantic Database under FamilyHart genealogy. Also you might try Genealogy.com. Your John probably is suppose to connect here I just have not found out where. And i'm sure Reverand Nathaniel Hall had at least one brother named John.
