I found the following on one of our french websites which may be of interest to you but i have not confirmed the info.:
Moise Gregoire m. Exina Charland Aug 4 1874 Wotton
Clarisse " m. Gregoire Thibodeau Apr 12 1864 Wotton
She is b. Mar 16 1842 d Feb 21 1869
Odile Gregoire m. Charles Thibodeau apr 22 1853 Wotton
She is b. July 15 1833 d. Feb 29 1916
Elmire Gregoire m. Joseph Augustin Charland-Francoeur May 5 1871 Wotton, they had a daughter named Emma m. George Picotte Jan 11 1874 St.Justin,Qc.
All the Gregoire are shown as children of Damas Gregoire and Marie Charland m. May 4 1875 in Wotton.
I have Damas' ancestors which I believe go back to Mathurin Gregoire.His great grandfather Jean Baptiste m. I believe Angelique Gareipy in Deschambault. If you'd like more info. please contact me. i hope this helps.
