Your comment: "I have found children of Joseph Duplessis and Josephte Turcot."
I cannot find a single marriage for Joseph Duplessis and Josephte Turcot any where between 1620 and 1799.That is where PRDH stops except for death dates. Actually the only Duplessis and Trucot married between 1620 and 1799 was: _______________________________________
