My father is going to give me a picture of a Walter Knaack and an Ida Knaack. He said if he remembers right they were taken in 1941 or so and that it states that Walter is 10 years old. I will probably know more when I see the pcitures for myself. I believe these are pictures of my relatives from Crystal lake, IL. I have been trying to find the connection for lots of years. The Crystal Lake, Ill Knaack's used to visit my great uncle and his family, and this picture was my great uncle's picture. I hope I can find more information.
