Trying to locate a family member of Lt. A.F. Harris, 7th Recce Regiment WW2

[randall klein]

Any help greatly appreciated.

The Royal Canadian Hussars Association has been contacted by a Dutch historian with a request to commemorate the liberation of a Dutch town in
April 1945. Specifically, they are trying a family member of the first soldier into the town which was, according to the war diary, a Lt. A.F. Harris of the 17th Duke of York's Royal Canadian Hussars ( 7th Recce Regiment, 3rd Div ).
We know Harris was born in Oshawa ON on May 6, 1919 and was one of 3 children of Henry and Mercy Harris. We also know he was a replacement officer.
Would any experts on Ancestry be able to locate any family members?

Thanks in advance.
