ACGS was founded in 1973 by Prof. Roger Lawrence and Lucille Caron Legasse. ACGS was the first genealogical society to focus on the ancestry of the Canadian immigrants to New England and grew to be the largest.

As holdings increased and membership grew, we had many homes until the purchase of the former Blessed Sacrament School in 1993 until we sold it and moved in 2020 to our current home at 1 Sundial Avenue, Manchester, NH.

Our mission remains as defined by our founders; we continue to serve as a resource center for the gathering, preservation and dissemination of genealogical and historical information.
