Sorry, I don't have Pierre Dion and wife Marie Moreau as Joseph Dion's parents.
I have Julien DION (Jean Dion & Marie Simon) and Angele Hamel (Joseph Hamel & Marie-Louise Fontaine) as Joseph's parents.
I did not find a marriage record for your Joseph Dion and Georgianna Chouinard in the Province of Quebec.They were most likely married in the US.
All I have is Georgianna's parents as : Felix Chouinard and Tatienne Gagne.
Felix Chouinard (Antoine Chouinard & Angelique Vallee) married Tatienne Gagne (Olivier Gagne & Scholastique Gagnon) on January 10, 1848 at Ste-Luce, Rimouski, Quebec.
Now, while I'm at it with this Dion line, I have the following.Your Joseph DION had a brother *Alfred*.
Alfred DION (Julien Dion & Angele Hamel) married Josephine Chamberland (Joseph-Cyprien Chamberland & Georgianna Drapeau) at St-Philippe-de-Neri, Kamouraska County, Quebec on January 26, 1892.
This couple had at least two children :
1- Clemence DION (Alfred Dion & Josephine Chamberland) married Joseph-Albert Roy (Antoine Roy dit Desjardns & Arthemise Pelletier) on September 12, 1916 at Ste-Anne de la Pocatiere, Kamouraska County, Quebec.
2- Joseph-Alfred Dion (Alfred Dion & Josephine Chamberland) married Gertrude Foisy (Joseph-Allyre Foisy & Marie-Blanche Nadeau) in St-Patrice Parish, Riviere-du-Loup, Quebec.
