Grainne Mhaol wasn't a pirate, that's a myth. She was a merchant - and like every single merchant along every coast in Europe at her time, she did some smuggling.

Pirates were people like the mass murderer Francis Drake, who hijacked foreign ships and sold them and their cargoes for profit.

Bonnie Prince Charlie is a standard among 18th-century Irish songs as well as Scottish. Not a great place to put your hope for freedom - but more of a symbol.
