He was born in Hallowell Township in Upper Canada in 1804 and moved to Cobourg. In 1835, he helped form the Cobourg and Peterborough Railway Company. He served on the Cobourg Board of Police from 1837 to 1841. In 1841, he was appointed sheriff for the Colborne District and later served in the same post for Peterborough County until 1856.
