I think we've been here before:
The term aptronym was allegedly coined by the American newspaper columnist Franklin P. Adams, by an anagrammatic reordering of the first letters of patronym (to suggest apt) to denote surnames that suit the occupation of the name’s bearer (such as Baker for a baker). Both aptronym and the synonymous euonym are rarely encountered. [Encyc. Brit.]
..but I don't think you bought it the first time either.
