I believe my husbands grandparents are the people you were interested in. I don't have their exact address at hand but my father in law, John, was brother to Robert and Idabelle Pyritz. Their parents were William and Linda and they lived on the south side of Chicago. If you are still interested in sharing the photo's I would love to add this piece of history to the family book!
