I don't know who is in the wedding on the bottom photo, but John is certain that his grandfather is the man standing in the top right corner.
And with the top two photos, the story we were always told is that John's grandma and grandpa eloped to Crown Point, Indiana the night before she was to leave with her family to return to Poland - because she was too young to get married in Illinois. But if that's the case, why the formal wedding? Maybe after the fact?
At any rate, what awesome photos - to leave so much to the imagination as to what really happened, so long ago.
