You might want to reconsider your doubts. In a number of Ameican publications of note, including the Johnson Publications, it was well-established that two of Peary's and Henson's sons have survived into their eighties, as of the 1978 publishing of these and other articles commenerating Mr. Henson. I don't know how you Wiki "scholars" authenticate the existence of living persons, but of these descendants, there hasn't been one refutation since. And understand, these two had the intelligence, and physical evidence to back up their claim. They might have long passed now. I'll try to get details and post them.  Otherwise, feel free to utilize the online resources of the Shomburg Library and Museum for  African-American history.   http.//www.nypl/location/shomburg.    Veryverser
