I'm related to a pirate!

Well, a fictional one... Through marriage... I'm reading Gene Wolfe's Pirate Freedom and was pleased to see there a French pirate with my wife's last name. Her dad came to Canada from the Netherlands, but a single French soldier had fled to the Netherlands some centuries ago and given his name as an inheritance. Was he a former pirate? (Probably not--family legend has him as a Hugenot soldier who fled for religious reasons.)

Random, I know. But fun.
