Looking for information on my great uncle Jacob Florian Heinz born-1897 Switzerland died July 9th 1940 in Montreal. He was buried at Hawthornedale cemetary in Montreal. His wife is listed as one of the witnesses the only name I have for her is Louise. They had a son James who died in 1927 also. I was wanting to find out Louise's maiden name and if they had any other children, also if she had remarried, so far I haven't been able to find anything more. Jacob Florian Heinz also went by John Florian Heinz.At the time of his death they lived at 5646 Fourteenth avenue, Rosemount Montreal.
