Regarding Joseph Zielke Family: I am not related to this family, but I just ran across a cabinet photo on eBay that says, "Joseph Zielke Family" on the back. The photo appears to be of a husband & wife with 5 children (4 girls & 1 boy). The family dog is with them and the house is in the background. If you are researching this family, you may want to look at the photo. The seller (star515) has it listed as, "FAMILY, CHILDREN W/ DOG ORIGINAL OUTDOOR VINTAGE PHOTO" and here is the link to it: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290383604150&ssPageName=STRK:MEWAX:IT
The photo is listed as a buy it now for $24.99, so I don't know how long it will be available. I'm an avid genealogist, so when I see photos with some identification, I like to let their families know about them. I have saved a copy of this photo, so if you can't find it on ebay, email me and I will send you a copy of the photo.
