Hello
I am not familiar to this family but I checked my BMD records for this area and I found a George Washington Wilkinson a bachelor of Granby Quebec who married a Florence Diantha Wilson of Dunham Quebec on Dec. 31, 1889 in Dunham Anglican Church. I don't know if he is connected in any way to your Wilkinson family. I don't have any family name of Jacob/Jacobs in my area. Hope this may be of some help
