Sylvanus lived in Wayne County, Indiana, near the Quaker Springfield Monthly Meeting, and emigrated before 1854. He was disowned by the Richland Monthly Meeting in Keokuk County, Iowa, in 1855 because he married a Baptist, though she had Quaker ancestry. He was a physician. He joined the 24th Iowa Volunteer Infantry as an assistant surgeon during the Civil War. He became ill during the Siege of Vicksburg; he remained in Vicksburg and died there. He is buried in the National Cemetery in Vicksburg.
