Gagnon Family Legacy - Ceramic Mug

Did you know that most people with the Gagnon name came from three sons of Pierre Gagnon (Gaignon) and Renee Roger of Tourouvre, France, who came to New France (Quebec) around 1637? Mathurin, Jean and Pierre Gagnon, along with their wives did much to populate North America with the proud Gagnon surname!
