There is a thing called "nominative determinism", that says that your name is more likely to match your occupation.
And it looks like a real effect. It is controversial but there are peer reviewed studies that confirm the effect.
My favorite: Chris Moneymaker, the poker champion. However I wonder if there was reverse causation at work: maybe his name and/or his family tradecraft of gold/silversmithing influenced him to try out competitive poker.
No idea if that was their original birth surname, but I wouldn't be surprised.
Too on the nose for a serious novel.
