I just ran across your email - which I can't remember ever seeing before - and see that it was over a year ago that you sent it! I'm terribly sorry not to have connected with you before now. Did you make your trip to the area and make any headway in your research?
My Hall connections descend from William Hall (b. England 1770, d. Pointe Levis, PQ Canada 1854). I don't have a record of a Louis & Susan in my research, however, will keep your email and contact you should I run across anything that might be possible. It really is a small world, Danny, and it wouldn't surprise me in the least that we can find an association here.
Did you get a copy of the Pickford & Stalwart histories that have been published? They can be quite helpful. I'll keep your information and anything else you'd like to send me and as I work will keep you in mind for anything that I might turn up. I would be glad to send you my Hall Family Tree to see if you can make any connection if you think that is something you would want.
I live in the area and have been away from the genealogy work for about a year, but hopefully will be able to get back to it in the months ahead. Please feel free to send me any information on your Hall's and I will do what I can for you, whenever I can. You can contact me directly at my email: firstname.lastname@example.org
All the best - Jan
