The will of Richard's brother William give you his brother's names and where they come from in England. LDS church has filmed the marriage registers. I started with the graves in the Dixie Cemetery and several family histories I found at the Ontario Archives. Did you know John's sister Ann married Alex Chalmers? You can find their marriage Registers of Upper Canada, they married 21 August 1841. I hope this answers some of your question. Happy Hunting.
