I would like to exchange information with you. I decend from WILLIAM HARRISON HAYMORE, a son of Mark and Tabitha.William Harrison had a daugter named Elizabeth Haymore. She is my G Grandmother. She married a James Arthur Harrell in Pulaski Co., VA. I too am searching for the Father of Mark. I have a very large book written on the Haymore line by fellow researchers. There are clues and assumptions, but no one seems to know for sure who Mark's father was. Can you please tell me how you connect to Mark and Tabitha?
