I have located Peter DUGAS aka Pierre DUGAS (born 1857 in Canada and died 1933 in Michigan, husband of Cordellia TREMBLAY, son of Augustine DUGAS and Clarice MAHEU) in the 1900 and 1910 US Census for Forsyth, Marquette County, Michigan under misspelled names. The corrections I submitted to Ancestry have been accepted. Both of these important sources now appears on searches of the correct name.
