I would rather see specific people rather than a general category.
Joan of Arc
Billy the kid
Vlad the Impaler
Eric the Red (or just a viking)
Yeah that would be cool though I wonder if it would be a bit jarring since everyone else is a character type rather than a character name. I probably would have preferred it if they'd gone that way and instead of having "Cursed Pirate" you had "Calico Kate" or something as the illustrations and rules bio could tell you she's a cursed pirate.
