I'm trying to get some loose ends tied up in my genealogy records. My great grandmother was Mary Vanderhoff, born in December 1874 to Abram and Frances (also referred to as Sarah) Vanderhoff. They lived in the Newfoundland/Oak Ridge area. She married Watson Henderson in 1894, and William Sehulster in 1904 after Watson died. What I am trying to find, is the maiden name of her mother. Any help would be greatly appreciated.
