I've been researching the ancestry of the Tetreau, Tetreault, Tatro, etc. family for over 40 years,and have gathered over 26,000 individuals as being directly descended from Louis Tetreau, who was in Canada by 1660. I don't charge family members for my research, nor do I send genealogies out over the Net, for privacy reasons, in which case I would need one's postal mailing address. I welcome anyone with this family in their background to contact me either by my e-mail address (email@example.com), or by mailing me at P.O.Box 234, W.Newbury, MA 01985.
Here are some of my favorite websites:
