Malvina Rivard (b. 1873) and James Murphy; Lowell, Massachusetts

I've been looking for information about Malvina Rivard (b. 13 Sep 1873), St-Leon-Maskinonge, Quebec) and James Murphy, her husband. She is the daughter of Alexis Rivard and Sophie Lesage. I have no information on James Murphy except for his name.

They were married in Jan 1894 in St-Joseph Church, Lowell, Middlesex Co., MA.

~ Where can I find the St-Joseph Church marriage records?

~ Does anyone know if they had children?

~ Did they die in MA or Quebec? Where are they buried?

~ Where is James from; who are his parents, siblings, etc?

I appreciate any direction you can give me ... Thank you!
