Marty's mother died when he was six. He was raised by his aunt and uncle in Switzerland until the family immigrated to St. Louis, Missouri. They moved to Stillwater when Marty was twelve. Marty lived with his father for a time, but they had a strained relationship as Marty grew older. Before the Civil War, Marty worked as a farmhand for local land owner Henry Jackman. At the age of eighteen he began an apprenticeship under Mort Webster, a Stillwater carriage painter. When news of the outbreak of the Civil War reached Stillwater, Marty enlisted in a local militia unit called the Stillwater Guards. Three of Marty's cousins also enlisted, including Samuel Bloomer.
