Cornelius Springer Hamilton was a lawyer and farmer in Marysville, serving his first term in the Fortieth Congress from the Eighth District of Ohio. Called home over family concerns about his suddenly unbalanced eighteen-year-old son, he was in the process of getting his son admitted to an asylum when the young man struck down his father with a wooden board, killing him instantly. The killer than attempted to murder the rest of his family but was apprehended before further damage could be done. Cornelius Hamilton was forty-six years old. He was replaced in a special election by Republican John Beatty. (By John Osborne)
