Alison: I have Susanne Mombourquette married to Pierre Landry in my tree. I have their parents as Pierre Jean Landry and unknown wife and Alexandre Mombourquette married to Pulcerie Dugas. I recently met with a Landry researcher and he confirmed that according to records, Pierre Jean's wife is unknown at this time.
My tree follows Susanne and Pierre's son, Aime Landry married to Elizabeth Cogswell, to their daughter Sophie Alice Landry married to Henry Placide Burke (Bourque) to their son, Robert Vincent Burke, who is my father.
If I can help you with anything, let me know. If you can't see my tree on here, let me know. d_cotorceanu
