Hi Kevina!
I found a photo of Mrs. F.W. Kraemer and on the back it says "Milwaukee, Oregon" So perhaps you are looking in the wrong Milwaukee. There are some other unidentified people in a photo with this same woman, but I don't know if they are Kraemers. I have been told that Gretchen Kraemer Elsken went to Oregon in 1946 to visit relatives there so that is probably when the photo was taken.
