Carl had a daughter , Allison (who would be a grand-daughter of Wayne). I can find some possible contact info for her and will PM it to you. At this point you know that none of the crash survivors are still alive and that two of them apparently had no children. I have not checked on whether any of the men killed in the crash had any children, but at this point you are probably going to find that the closest relatives to most of the crewmen are nieces and nephews, most of their brothers and sisters will have also passed on.
