The first picture below was not identified in the album, BUT I know I've previously scanned it in another collection and right now I can't find it. I searched for various names or wording like "unknown" but nothing came up, but I know I've scanned this same picture.
So I searched for Vinke pictures and sure enough I found the family photo that Gay Wiskus had, so now I had the name of the husband and wife.

Unfortunately I can't find anyone who has the children identified...guesses can be made based on their birth year but that can be dangerous by guessing incorrectly.
