Suburban house, 1920's.jpg

With architecture like that and a palm tree in the yard my guess would be California more than Canada.

Quite likely. I was presented with a thick envelope of negatives, over 200. A mixture of 108, 116 and 122 formats that came from the estate of a Canadian man. His wife administers a trust that has Canadian members so I'm hoping that she can give me contact details of his Canadian relatives and that I can send the scans / negs back to them.
