John is William's brother. They are supposed to have come from Ireland in 1818. At least William did. I think John came a little later. his first wife died before they came to Canada. I have their marriage date as 1800, in Canada. Does this agree with your records? I have been trying to get back from John & William in Ireland, but no luck so far. I don't know their parents names. I do know that William married Mary Benn in St.Anne's in Dublin, Ireland. in 1796. Their children were, Edward, William, Anne, John, James, Michael and Jane. We are related through Edward.
I would like to correspond more if this sounds like your family connection.
Hope to hear from you. Donna
