I need assistance in locating grave sites at Oak Grove Cem., Uniontown, Pa. Does anyone know where the burial records are located? (if they exist). I understand it is a very large cemetery. Seeking the location of the following graves Rev. William Henry Ellis (d.1931) and his wives, Rev William (d.1881) and Susanna Sembower Ellis(d.1890's), Eva Margaret Ruff Sembower (d.1853) and Rev Alphus H. Sembower (d. abt 1930).
