While the deaths were caused by illness, it could conceivably be that the combination of the parents' genes resulted in a genetic condition which made those children more susceptible to that specific disease or that affected their immune systems in a negative way so that they were more susceptible to disease. Of course, there is no way of proving this, but I do think it is a valid possibility. Peace, Part of the Tree, Greg
