While Clark was serving in the war, his youngest child, Ella, died on July 13, 1863, at the age of ten. Clark’s wife, Philania (Wilson) Clark, left him for another man. When he returned from the war, Clark moved in with his brother, Sheldon Clark, and his family. He became a cobbler, repairing shoes for a living. His life after the war bore little resemblance to what it was before.
