Is it in the ancient city of Persepolis in Iran? There is supposed to be some graffiti by him there. My wife's family is distantly related to Dave Livingstone and my real family name is Rowlands (my dad was adopted). The male line comes from North Wales, very near to where Stanley, whose real name was John Rowlands, was "brought up" in a workhouse. So quite possibly I'm related to Stanley and my wife to Livingstone. My elder brother's first names are John and Rowlands.
Sorry if I'm wrong anyway!
