Thanks Jill, I will definitely check out Wilson’s database!
The biggest challenge for me is the sheer abruptness of how the Canadian records end. So far I’ve had no luck finding Robert Brown’s mother (and John’s wife), Robert & Mary’s marriage record, or even exactly when they came to Canada. For all I know, they may have even immigrated to the United States and then come to Canada – I have no idea. The 1842 & 1825 Canadian Censuses are so vague, and the digitized records carry very few column titles over across images, so it gets confusing doing electronic research from home.
