A Sibley Family Tree

Solomon Sibley married the daughter of Ebenezer Sproat, a principle in the earliest corporation to acquire Indigenous land (in Ohio) from the federal government. Sibley became a Michigan Territorial judge, and owned extensive property in Detroit, sometimes in partnership with Territorial Governor Lewis Cass. His treaty signing sons inherited some of his property, and son Henry went on to wealth and political prominence as a fur trader, land speculator, mine owner and governor of Minnesota. Solomon’s daughter married the personal secretary of Lewis Cass, banker and Indian agent Charles C. Trowbridge.
