I have a good deal of information. My Grandmather was also the daughter of J.C. & Augusta Dorpat, & she gave me a variety of pictures & information. I believe you must be my children's generation. Your Grandfather, Mike Kruck, was known to me. As a toddler, he sent me a pair of boots from Brazil, where I believe he was stationed in the military. They are bronzed & in my position to this day. He & Dee last visited me in Hilton Head, SC, where I still live. This must have been the early 90's
I will send you what info I have.
