Hi,
From what I've gathered, there seem to have been at least three different branches of Brownells in Fulton County that nobody that I've heard from has been able to connect. Your names don't sound familiar to me, and I just did a quick look through my Brownell folder and didn't see anything on them. I've mostly collected records for NY up to 1860, as that was about the time my Brownells left NY. I think your best bet would be to go to www.genforum.com and go to the Brownell page. It's a great place to find information & it will keep you busy for a while. Good luck with your search!
