I would be interested in reviewing the material you mentioned below. I am trying to find a Benjamin Rolfe who was born in Dudswell, Wolfe County, Quebec, Canada and married Betsy Moulton on 22 Feb 1821 in Eaton, Compton County, Quebec, Canada. the family appears in the 1825 Canadian Census with one son and in the 1831 Canadian Census with 2 sons and a daughter. They do not appear in the 1841 census and later.
Therefore, they immigrated after 1831 probably to the states. Many inhabitants from The Eastern Townships of Canada moved to Vermont, Indiana, and Michigan.
Thanks for your response.
