I am sending to you what has been published in the book,
HALIFAX COUNTY VIRGINIA MARRIAGE BONDS 1753-1854
The record as transcribed:
24 Jan 1751
Bondsman: Alex Harrel
I am not related to these people, but simply wanted to answer your call for help. I would question that date of 1784 IF the DOB is 1770. That would make him only fourteen years of age at marriage, Possible, but not likely.
Realize this is a MARRIAGE BOND book when they applied for license to marry.
Under the listing for Larkin GRAVET were the following two people that may apply somehow to your research.
NAMES: Charles GRAVETT and Henry GRAVETT.
Hope this little reference helps. I consider the Bond Book to be a dependable record.
Have fun sorting through it all.
