Their story of capture and survival in Quebec


Professor Roger W. Lawrence

Publication Date: Summer 2015


Professor Lawrence spent 30 years researching the captives of New England taken during the French and Indian War. Much has been published about these captives but Roger was compelled to find new details from contemporary sources. He has examined, extracted, and translated vital information in marriage contracts for those captives or prisoners who were assimilated into the French Colony. This is an excellent research tool for New England colonial descendants as well as for French-Canadian descendants of these captives. Some of the English ancestry goes back to Royalty and Nobility.

Manchester Historic Association – Manchester’s Immigrants: Then & Now
Opened March 10th


The Manchester Historic Association is excited to announce that it is opening a new temporary exhibit, “Manchester’s Immigrants: Then and Now,” at the Millyard Museum on Bedford Street.  This exhibit will showcase photographs documenting the lives of immigrants from all ethnic backgrounds, from the earliest Irish, French-Canadian and German mill workers to the more recent Bosnian, Sudanese and Bhutanese arrivals (just to name a few).  By juxtaposing extraordinary photos from the MHA’s own collection with images of current refugees and immigrants as documented by photographer Becky Field, Manchester’s historic role as a social and cultural melting pot will come into full focus.  We felt that members of your organization may be interested in visiting this exhibit.   Attached, see more about the exhibit in this flyer.


Catherine Baillon

In 1999, we were fortunate in having the opportunity to publish an excellent article on the well researched line of Catherine Baillon: René Jetté, John P. DuLong, Roland-Yves Gagné, and Gail F. Moreau. “From Catherine Baillon to Charlemagne.” American-Canadian Genealogist 25:4 (Fall 1999): 170-200.

Through the generosity of the surviving authors we have obtained permission to make this article available on our website. To read or download this article, simply click on this link. Our appreciation to John P. Dulong for making this possible.
