Dunno why I suddenly remembered this, but it reminds me of an anecdote. My mum was booking a hotel for some friends, whose name is Thompson (the p is silent, for those not familiar with it) and so she told the hotel their name was "Thompson with a P" (Thomson is also a form of the same name). When they got to the hotel, it took the girl at the reception quite a while to realise that the person who wrote down the reservation had written it Ptomson.
