Maybe. He could also be related to Mrs. Robinson of Simon and Garfunkel fame and also Will Robinson of "Lost In Space" and perhaps even Robinson Crusoe.
Also, I once had a dog called Mr. Robinson, so there could be a connection there too.
Robinson is also not his original name. Original name is Stephen Christopher Yaxley-Lennon. He changed his name I guess because he has a past history of criminal convictions. Break from his past I guess.
