Hello, according to my uncle who has been working on our family tree for years the parents of Therese Filion who married Augustin Rochon on 23 Jan. 1758 at Lachenaie,Qc were:Francois Filion and (Marie)Therese Marsan.His information came from mariage records.(It actually looked more like "Maron"instead of Marsan, but I have never found any "Maron" marriages.)It seems the fancy writing on the marriage records was rather hard to decipher.Marsan is often Mercan dit Lapierre or Marsan dit Lapierre....Francois Filion, son of Antoine F. & Marie(-Francoise) LAtouche.........Therese Marsan(dit Lapierre ) daughter of Francois M. and Isabelle Elisabeth Desroches............Augustin Rochon son of Francois Rochon and Charlotte Gingras(marr. St-Augustin 3 Feb. 1728.)However I am not sure about the date of death for Therese,I'll have to check out a few things. I hope this helps you. She is my ggggg grandma.Feel free to E-mail me directly.Bye"cousin"! H.
