I, too, am researching my ancestors. I will explain. I found a bunch of old photos in my possession. Just items purchased over the years. I found an old picture from Geneseo, IL and on the back it states "August Ristau". I decided to look on line to see if he belongs to someone. If this gentlleman (pictured with a lady on thier wedding day) is part of your family, please let me know. I can send you a scan if you like.
