I am a decedent of the O'Briens that lived in Wallace in the first half of the 1800s. A lot of my information is spotty and I am hoping for some help.
My 4-greats grand father was John O'Brien (1789-1844) who is buried at the St. John's United Church cemetery in Wallace. I know quite a bit about the family from that point forward, but I have nothing from before.
John's wife was named Mary Margaret (unknown maiden name) and is buried with him in Wallace. She was born in Quebec in 1791 and died in Wallace in 1882. I don't know where was was born in Quebec.
I know nothing about John or Mary's parents, though I know that two O'Briens were given land in the Wallace area in the 1780s at the end of the U.S. Revolutionary War. My conjecture based on their ages is that they were father and son and the younger of them is John's father based on John's birth date not long thereafter. I have no proof of this however and have lost the details on these two loyalist O'Briens.
Any help would be appreciated. I would of course be happy to share everything I have on John's decedents. My family flows through his son Joseph (also buried in St. John's).
