The wonderful nsfl has this to say of Lord Lucan and his heir:
"His heir (I forget whether he took the title or not), George Bingham, often writes his father's name down when playing that game in which people pair off and one contestant has to describe a famous person to the other. He, the heir, is a charming fellow (despite this habit) but a bit too keen on the internet perhaps. But who am I to talk?
"(He thinks his father sent a hood into the flat that night to steal some heirlooms that he might not have won in a divorce... And that his father committed felo-de-se in the Channel.)"
