Charles I am researching the family of Samuel and Margaret Birch. I know they moved to White Co. from somewhere in Tenn. and the 1850 census lists Mary A. and Ephraim as living in the house. Ephraim is my gggrandfather. There is a big difference in ages between Samuel/Margaret and Mary/Ephraim.Are you sure these a parents and not grandparents and do you know of any other siblings? I know Ephraim/Mary were born in Tenn, but have no idea where, so am stuck at present.
