Does anyone know of a cemetery that has a Harriett Roberts, born Sept. 8, 1820? She was the daughter of John T. Roberts and Esther Durnil, who are both buried in Martinsburg, along with most of their children and grandchildren. Harriett is the mother of George Mifflin Dallas Roberts, no father known. I've been trying to find her death date and location, but have not been able to find anything after the 1850 census. Any help would be greatly appreciated. Kathy Verona NJ
