As to your mention about the informations related by Mrs. Manseau.. she meant Jeanne (girl) that was born on 11 apr 1659. Jean (son) was rather born around 1682 and died before 1756 as mentioned on a mariage register of his son Jean.
So allyour line is as;
Eustache Pineau (M) 5 apr 1869 in Matane + Louise Bouchard
Honoré Pineau (M) 18 jan 1931 in Rimouski + Déesse Fournier
Jean-Baptiste Pineau (M) 1 june 1785 Rimouski + Geneviève Lévesque
Jean Pineau (M) 12 october 1756 in Cap St-Ignace + Geneviève Méthot
Jean Pineau (M) 1710 in Beaubassin Acadia + Anne Chiasson
Pierre Pinot (m) 14 may 1658 in Trois-Rivières + Anne Boyer
Paschal Pinot (M) 4 febuary 1620 at Sargé lès Le Mans, in France+ JehanneMarteau
