Gayle, I am so sorry to hear of your daughter's death. My oldest daughter has celiac sprue disease. I had never heard of it but it is becoming more common. I would assume it is inherited. Her knees and elbows were breaking out so I took her to several dermatologists before finding it to be dermatitus herpetaformus. The doctor tried to control it with pills, she takes Dapson, a medicine for leprosy. She also has to watch her diet, no wheat, oats, rye, or barley. That eliminates a lot of things you wouldn't think of unless you read the label. No distilled vinegar, no catsup, mayonaise, mustard, etc. I have read that a large population of Ireland has this disease. I have often thought that ancestors could have had this disease and died not knowing what caused the death or calling it something else. Sandy
