Here is a photo taken about 1939 of the family of the eldest son of Wilhelminia (Schmidt) and Paul Richard Junghans.
(From left to right)
Back row: Harlow, Della, William and Ken Junghans
Front row: Marian Junghans
I had originally labeled this photo with "Bill Jr", but from looking at the photo, it looks like William (or Bill Sr) wearing the hat, but difficult to tell.
