a nice example from the fourteenth century:
Paul Booth, a historian at Keele University in England, found three examples dating from 1310 and 1311 of a man known in legal documents as Roger Fuckebythenavel.I predict that Roger will soon have one of the most famous names in English history.
Booth said he believes Roger was not the bearer of a very unfortunate family name, but rather it was given to him derogatorily.
"This surname is presumably a nickname," Booth told Medievalists.net. "I suggest it could either mean an actual attempt at copulation by an inexperienced youth, later reported by a rejected girlfriend, or an equivalent of the word ‘dimwit,’ i.e., a man who might think that that was the correct way to go about it."
