Curiously, Frank never mentions his mother by name. Her maiden name was Susan Moore. She was born in 1818 in Miami county, Ohio. Notes from a family bible place her marriage to Michael Stahl in 1840. Altogether, the couple had 8 children: Frank, Lavinah, Jerome, Lloyd, Sarah, Florence, Mary Belle, and Martha.

She died in 1901 and is buried in the Auburn cemetery, Shawnee county, Kansas.
