Looking for help to locate my ggreat grandfather Watson Pleasant in the 1870 census. This family is listed on the 1880 census living in Williston, Barnwell County, South Carolina.

Watson Pleasant, wife Sarah Roberson Pleasant and kids, William, Millie, Rivanna, Isaih, Joseph, Nancy and Malachi, and his mother, Mariana is living with them.

I have searched for several years and turned up nothing. Just last week I searched the South Carolina Archives and found the 1860 Roll Of Citizen and found Watson Pleasant listed he was residing in Barnwell, South Carolina.

Just having a hard time trying to locate this family in the 1870 census any suggestions on how to break this wall down.
