I do not have any info on the Pietz family, only a photo, probably a wedding photo, of Mr. & Mrs. Fred Pietz. I am assuming it was taken in the early 1900's. The photo album belonged to my husbands mother. Her family names were Haberman/Hepperle and they were from Leola, S.D. From the little bit of research that I did a number of years ago on the pictures in this album, I found a couple of listing that said Fred Pietz married Anna Quast - but who knows?
If you would like a copy of the photo, I will be happy to send one along. Just send me your snail mail address as I do not have a scanner.
