The funny thing about the name "CRUMP" It is not that common a name, When I moved to the USA in 1957 I was interested in Jazz music, There was a LosAngeles California Radio jazz station, they had a disc jockey name Don CRUMP!! Well, I called the station and talked to him one day, told him I was a "CRUMP" Oh he said, he and his family are from the south USA they own several restaurants there, so I said "Well you could be a relative then" he said probably not, our family is Negros!! or Blacks, as they are now, called. Apparently, slave owners. raped their slaves and their children took the last surname of the owner.
