Northern New York American-Canadian Genealogical Society

Who do you think you are?

Our society is dedicated to finding that out. We help you research  the genealogies and familiy histories your Clinton County ancestors. Our genealogical library is located in Keeseville, NY, and contains about 5,000 volumes dedicated to local research. We have many books on Clinton County families, books of local church and cemetery records, many Quebec parishes, the Loiselle Marriage Index and other genealogical treasures.  Our librarians are all more than willing to help you find your missing Clinton County ancestors. We all love it when we can find the ancestor you've been searching for!

We will also come to your organization to talk about genealogy. Our speakers have given presentations in many locations in Vermont and New York as far away as Syracuse. In recent years, we have been talking at schools in the area. Call us and we can make arrangements to talk with your group.

Our society has helped organize and print family tree books for local families. We also do research for authors writing books on the rich history of the area.

Identify And Describe The Management Organization

The Northern New York American-Canadian Genealogical Society was founded by William Marquis in 1983 to help other find their French-Canadian roots. The basis of our collection is the books that he so generously donated. We used to publish two journals a year with stories on the genealogies of Clinton County. Now we publish a double journal and are always looking for your stories to print. You can see some of our articles at  This year's research theme is Civil War ancestors. We also have more than 3,000 photos of local venues and events online at . We are a 501(c)(3) organization.

About This Building And Site

Last year our whole library had to be relocated from the old Keeseville High School. We are now in a building at the bottom of the hill on Vine Street.  Check out our site for the map.    We're always looking for librarians. We can train you on how to use our library. You don't have to be a board member to be a librarian.
