Harry Garth WANLESS appears on the NSW Electoral Roll to 1980
Wife Dulcie Olga is with him.
He lived in the suburbs of Sydney with various occupation including toolmaker and milkbar proprietor.
I am happy to type up the listings if they are of interest to you.
From 1963, Dulcie Olga is not at the address which agrees with the divorce finding.
Sharing the addresses after this is Joyce Rubina WANLESS.
