I have found the baptism of Celina / Salina Etu, daughter of Pierre Etu & Adeline Renaud.
Celina/Salina was born & baptized 15 Oct 1852 In Sainte-Mélanie, Québec
The church record said that the parents were "from this parish". The godfather was Pierre (Senior) Etu.
I have not found yet information on this Pierre (Senior) Etu but he belongs to my same ETU/HETU family.
Between the begining of Sainte-Mélanie in 1832 and 1860 I have found 11 Etu families who had their children baptized at that parish. They are all descendant (3rd ot 4th generation) of Georges ESTU and Marie LOISEAU who were married 9 Feb 1699 in Boucherville, Quebec,
