We are satisfied that Giles Richerson and Jane Richerson are the parents of Thomas Richerson, our previous oldest proven.
Giles Richerson died in November 1804, John Richerson, administrator, and his daughter Frances and her husband Benjamin Hurt sued with the other heirs to have the estate divided.
The wonderful Library of VA has the "actual" (photocopied) report of the division of the estate online.
The nine heirs drew lots, each receiving slaves and bonds to equal 251.16.9 pounds.
Thomas received slaves ARMSTED and ISBEL.
Reuben, Thomas and Mordecai Broaddus were ordered by the court to manage the division.
Ten years later, Thomas died. When his estate sale was reported, income was reported from the hire of his slaves ARMSTED and ISBEL!!
The nine heirs of Giles Richerson (and wife Jane is not mentioned, so we believe she was dead before her husband), are John, Thomas, Frances and Benjamin Hurt, Elizabeth (widow of Henry Stuart, Jr.), Salley, Molley, Jane, Lucy, and Martha (Patsy).

Now, it seems more than likely that the Joseph Richerson (various spellings) married to Elizabeth, who had sons who moved to Green Co KY,
and a son Giles who stayed in VA for a while and then supposedly moved to IN and TN. The unusual name Giles, the Caroline County setting, and a few situations where the names appear together:

In 1765, Giles Richerson, Joseph Richerson and Moses Penn proved a mortgage from William Richerson to John Taylor, Gent., in Caroline Co.

And Giles' wife was Jane Johns. Another surname to work with.
Hoping to hear from others working with these lines.
