Flat Island, Bonavista Bay, Newfoundland

This is Flat Island, most likely in the 1940s or 1950s, although I can't say for sure since I don't know where the photo came from. I found it online a few months ago.

If anyone can date this photo, or knows who the folks are in the foreground or even whose house is whose in this picture, that information would be greatly appreciated!!!

Having never been there, the only thing I know for certain is that we are looking at St Nicholas Anglican Church on the right! There is also a cemetery in the photo directly in front of the church, one of three cemeteries on Flat Island.
