I have no idea yet if my grandfathers' family has roots in Hanover, but when I came across your reference to Canada and the year, it sparked something. My grandfather was William Henry Klabunde. He was born in Pembroke, Ontario on Dec. 20, 1894, died Aug. 14, 1958 in St. Lambert, Quebec. I might mention also that my GF only had one son but he never had children to carry on the family name. If you have any other info on Klabunde's in Canada I would be very interested.
Thanks
