Dear Gary,
No progress made here. In studying the Hicks of Spottsylvania Co. Va. I find the following

a James Hicks b. ca 1750, who is said to be a father of Thomas S. Hicks b. 1771, Thomas married to Lucy Alsop. (Elizabeth Pendleton's mother was an Alsop....)

James is said by one rootsweb contributor to have married a second time to Elizabeth Harris, (sister to Thomas's mother Mary Harris) but no children are given.

The 1790 & 1800 tax lists of Spotsylvania Co. show only a
Peter Hicks. Most researchers are giving his date of birth as 1769, which I believe would be a little too young to be a father of our Joseph Hicks.

Lastly the 1810 census lists of Spotsylvania reflect the following;

1810 Virginia Census Index Hicks
Joseph Spotsylvania
00100-10100-01

Andrew Spotsylvania
00110-00100-01

Peter Spotsylvania
31210-21010-01

Thomas Spotsylvania
23020-31010-09

I wish I had a definitive answer, but I do not....

Sincerely,
Vicki Piper
