I'm looking into my wife's family tree. Her mother, Dora Violet Clements, married John MacPherson on 12 August 1944 in Hanwell, Middlesex, England. They had one child Vivienne (my wife'a sister). John was a private in the 5th Canadian Pioneer Corps, he was killed on 25th July 1945 when Vivienne was 2 months old. He was buried in Berwick Cemetery, Ontario, Canada. His father was Donald MacPherson but was deceased by the time John and Dora married. But all I have on John's family. can anyone shed some light?
