The Blackburn Akers who m. Susannah Skaggs was Blackburn Akers who married ? Blackburn sometimes seen as Susannah's son.
Blackburn Akers who m. Susannah Skaggs marriage didn't occur till November 20, 1786 in Montgomery Co., VA. This is the date listed in Anne Lowry Worrell, "A Brief of Wills and Marriages in Montgomery and Fincastle Counties,Virginia: 1773-1831". When I get to Virginia side of the Akers Family I will check this date in the records if I am able to.
Since all the children that I have for Blackburn (1) were born before that time except for Adam Akers, Sr (b. 1789) Susannah Skaggs could not be the mother of my ancestor (Valentine Akers b. 1762).
