I was confused earlier, I didn't realize that you're looking at Dryden Bryant as a possible sibling to George Bryant, now it all makes sense. I thought your were one of the descendants to Dryden Smith Bryant, son of George Bryant. Anyways now that it's clear as mud! I have info on the descendants of George and Rachel, especially my direct line which is from Thomas, George's son. You can view the famimly tree on-line at rootsweb. It's been a while since I've updated the information but it shows the lineage.
I can tell you that George and Rachel Bryant/Briant (In England it was spelt with the "i" and then changed at some point in Canada with the "y"). They lived in a house in Quyon, Onslow Township, Pontiac County, Quebec, where all the children were born. The area is mostly farmland, and the house sits on a very large plot, not sure how many acres but the house is still standing in it's original state (I have a picture I could send if you give me your email). I'm disappointed that I can't even find my computer with my tree on it or I could give you more info but hopefully that will turn up soon.
You can find the gravestones for some of the family in the St. John's Anglican Church and Cemetery in Quyon, Onslow Township, Pontiac County, Quebec. You can view them on-line at
