Louisa Co., VA 1793 - William Thomason / Unity Hicks / Temperance Dumas

From my research notes I find the following
wondering if anyone else can confirm the correctness of this info.

Notes By Dennis J Yancey dyancey @ miami.edu
as far as I know:
William Thomasson was the son of Samuel Thomson and Ann Payne
William Thomasson married 1st Elizabeth Hallom
and second Unity Hicks/Hix

Unity Hicks/Hix was the daughter of Prewid/Pewid Hicks/Hix
and Temperance Dumas.

Temperance Dumas had first married Robert Yancey who died in 1746. That is why in the will Charles Yancey is referred as a brother (albeit half-brother) of Unity - they both shared the same mother - Temperance Dumas a lady of French origin.

Many researchers believe this same Temperance Dumas married (2nd) one Samuel Thomasson who died in 1753 in Louisa County - and that the marriage to Prewid Hix was her 3rd marriage.
