I was looking on the genealogy website and you mentioned your brother as being Joseph Roy Zacharias. I also noted that you had questions concerning polycystic kidney disease on the message board. I had a friend at Fort Campbell KY some years ago that has got to be your brother. He mentioned to me that he had a sister named Twyla and he went into detail about his dad and other family members passing of the disease. I last spoke with him via instant messaging right after Sept. 11, 2001.I know he had great concerns about the disease since the other family members had it. I tried to find out as much information as I could for him at the time. I hope he is doing well.
