I'm Frank's Great-granddaughter. Pete Slabaugh (Luther V.) was my grandfather.
Samuel couldn't have been in the Civil War:
1. According to Ohio Marriages he and Anna were married on August 26, 1860.
2. Daughter Josephine was born in 1861 (1870 census).
3. Son Hiram was born in 1864 (1870 census).
So, if he was in the Civil War, he must have gone AWOL at least twice! ;-)
