Nice to hear from you. Yes, I believe we are researching the same families. I haven't had any luck in finding any further info on William L Hudson -- there are other Hudson/Hodgson families who settled in Amherst, Guysborough and Annapolis Valley (their William was also born in 1777, Yorkshire).
I have Catherine Glennie b. 1813, Minudie to John Glennie and Mary Ann Dickson. I am still trying to find info on John Brenton Donovan who married Sarah Jane Hudson, daughter of Catherine & William. I know that John was a tinsmith and plumber -- marriage records list parents as Henry and Susan, but other info is contradictory. They eventually moved to Truro where their daughter, Jessie Lillian Donovan, married Flemming B McNutt -- they are my great grandparents.
Look forward to hearing from you!!
