The Brocks were living north of York (Toronto) in Vaughan Twp. at the time of the Upper Canada Rebellion in 1837 and some family members were arrested as rebels. I am related to this family by two sibling marriages. They were not related to Gen. Isaac Brock.

We know that Mary Ann Blair was the daughter of William and Jane Blair. The family tree that connected Mary Ann to our Blair family tree had a number of errors. If William and Jane were my relations her maiden name would have been Brock. We are looking for proof. We know that there were a William and Jane Blair living near Perth Co. who were not our relations. We have no family history as far east as Perth County. We therefore have three reasons to be doubtful of the family tree we obtained the information from: errors, location, and two William Blairs married to a Jane. Mary Ann's marriage registration did not have her mother's maiden name. We cannot find Mary Ann's birth registration either. What was Jane Blair's maiden name? Do you know who Mary Ann's other Blair relations were?
