I am 75% sure that I am a decendent of the Freemen Epps you list. My Great Great Grandfather was Alexander Epps who we believe is the son of Freemen. He was from Person County, North Carolina and mulatto. It is believed that he was Sappony Indian and white.

If you want to share information I have a sketch of Alexander and a lot information on him and his family. Please just email me and I can send you what I have.
