I know that you posted several years ago but I just ran across it, looking for another ancestor.

Cornelius CAIN was my gggg-grandfather through Margaret SLEETH, Cornelius's second wife. His first wife was Sarah Hyatt. I do not have a list of the Cornelius/Sarah line, but I do have the Cornelius/Margaret line.
I have done no research on the Cornelius/Sarah line.
However,I do have Sarah's death as Aug 17, 1790 - Rockingham County, VA

If I can be of any help with information on the Cornelius/ Margaret line, please let me know.
