Thomas Miles Morgan SR and Catherine

Good morning everyone. Here is my brickwall: Thomas Miles Morgan Sr. born in 1790ish in either VA or SC. Depending on which Uncle you believe...lol I"m searching for information on him and his wife, Catherine, who's maiden name is unknown. Most of my Morgan ancestors ended up in KY, as did Thomas SR and Catherine. My line goes like this:
Thomas Sr and Catherine Morgan
William Miles and Mary Ann Rudd
Jeremiah Miles and Julia O'Connor
George Morgan and Samantha Munsell
Jessie Henry Morgan and Catherine Malaric (these are my biological grandparents)
Muriel Morgan (my mom)
and me
