My family is from Lac Mégantic, Quebec. It's near the US border, Maine to be exact. Maybe you should dig around that area. I don't know much about my great great grandparents, but my grandfather was Joseph Arguin (born in 1923), he had a brother name Magella, the others I don't know. I hope that helps. Untill i'd found this site, I never though there was so many Arguin on this planet.
