I am seeking information on Thomas Boak of Charlevoix, Michigan. He was 40 at the time of the 1880 census. He may have been born in Canada and possibly had a wife named Elizabeth. His son Gurley was born in 1861 and married Margaret Jane Saunders in Charlevoix in 1881. His daughter Harriet (Hattie) married Henry C. Cooper there in 1882. He also had sons Thomas and William who were born in Wisconsin.
