You seem to have much information about the Hamelins of Canada. I believe my great grandmother is a descendant of Rene Hamelin who went to the LaPrairie area, and possibly the daughter of Louis Hamelin. Her name was Marguerite Hamelin, b. abt. 1826 and who married a George McBeth,b. abt. 1820-21 and is believed to be the son of Francois McBeth and Marie Luce Guibault Francois McBeth's father, George, was in the fur trade.
