Oops... I copied your post and didn't add my own material - I guess it's true about the mind going first ...
Cornelius Watson is my gggrandfather, b. 1828, Ky. I have strong reason to believe his mother was Elizabeth, b. 1790 in Pr. Geo Co., Md. He died in 1865 in a prisoner of war camp in Indianapolis, Ind., at the end of the Civil War. He is my "brick wall". Blair and I believe that his gggrandmother, Martha, and my Cornelius were brother and sister. We are looking for evidence to support our theory.
My Cornelius' children are as follows:
(by first wife, Maryann) George W. (1849) and James (1853),
(by 2nd wife, Elvira Johnston, b. 1832 Ky.) Andrew J. (1855), Henry F. (1860); daughters: Harriet Ray Watson, Eliza Catherine Watson (all b. in Mo.)
Andrew J. Watson m. a Hibdon
Eliza C. Watson married a McDowell
Henry F. Watson m. Rosa Bodine
There is a marriage in Pr. Geo. Co. that might be the connection we seek:
CORNELIUS WATSON m. Elizabeth DAVIS
March 19th, 1807, in Prince Georges Co. Maryland
If anyone knows anything about this couple, I would be interested in hearing from you. The dates all line up, but anything is possible....
