There is a character in a portrait named Sir Cadogan in the Harry Potter series.

Ah yes, Sir Cadogan the Nutcase, I remember him.
I like the name. It's interesting. It sounds like, well, a knight. Probably because Sir Cadogan is the first time I've ever heard it used. But I like the name even if a famous bearer is a crazy dude.
