I am looking for information on William R Sanders (1824-1903 born in SC) and Mary E Moore (1822-1899 born and dying in SC), these are my gg grandparents. I have traced my tree all the way back to them but have hit a brick wall at them. If anyone can point me into the right direction I would appreciate it. I know Williiam lived with his granddaughter Sallie E Singleton outside of Charlotte, NC according to the 1880 census. I know that Mary and William are buried in Westminster, SC because I have seen the cemetery. Thanks for any help

My lineage is as follows:
Marc-Charles J Sanders-James Gary Sanders- Charles Gary Sanders-William R Sanders

Thanks
