Trying to get info on my great-grandparents: Harrison Ferdinand Gregory (born 7/14/1867, died 9/19/1930) and Martha Alice Dugger Gregory (born 1/16/1868, died 3/29/1939). They were married 3/18/1903. Two children: Lydia Oma Gregory and William F Gregory. I know Harrison was a blacksmith. I am trying to find where they are buried.
