Hi Doug,I just recently joined this web site so I'm not really sure how things work around here.I noticed your post and not really sure exactlly what you are looking for.I have some documents that match the names of people you might be looking for.
Joseph Ducharme b Nov 12, 1833 at Ste Elisabeth.Married June 21, 1854 at St. Joseph, Ont to Marie Papillon (parents Baptiste & Marie Belair).Married in the home of his parents by Fr. Schnieder.Migrated to Windsor, Ontario March 6, 1866.His parents were Jean Baptiste Ducharme & Veronica Tessier.
Jean Baptiste b Feb 28, 1814 at Ste Elisabeth. Married Jan 10, 1832 to Veronica Tessier (parents Jean Batiste & Therese Huppe-Lacroix).They appear on Huron County, Ont. census of 1851
I also have more if you are interested.
My Grandfather was Blaise Kuno Ducharme and lived in St. Joseph, Ontario.He's probably in the same cemetary you visited (I can't remember the name).
The Joseph to which you are referring to would be my grandfathers, grandfathers dads brother (I think, if I've counted that right).
Let me know if you would like copies of the documents I have.They go back to Nicolas Charron Ducharm b 1589.
