Pearl Grandstaff was married to great grandfather, Harvey Manis. Their first child, my grandfather was Carl J. Manis (whose daughter, Phyllis Ann Manis, was my mother). My great great grandmother (Harvey Manis' mother, Sarah Belle Robinson Manis) married Enoch Grandstaff as her third husband and my great grandfather, Harvey Manis and his brother, Harry Manis, lived with them for a time. I believe her second husband was probably Harris Keys.
If your family tree follows this line, perhaps you could verify and take this farther for me. Thank you.
