Why do most generated names come out English?
Because the roll is weighted, not uniform: the English style has a 35% chance of being picked, double the weight of Dutch or French (15% each), reflecting English dominance in Caribbean piracy of the period. To force another nationality, pick that specific theme instead of "all".
What does the quoted epithet in the name mean?
It is the crew nickname, the name a pirate would be known by on other ships, either in "Color + Body Part" form (like "Ashen Compass") or as one of 51 fixed adjectives (like "the Cutthroat"). It splits 50/50 between those two formats whenever the epithet option is on.
Are the "legendary" names based on real historical pirates?
Not directly: they are 49 fictional epithets built to sound like classic pirate lore ("The Reef Tyrant", "Old Ironsides", "The Flying Dutchman"), inspired by the genre but not mapped to any specific documented corsair, unlike the first and last names in the 4 national pools, which are real period-appropriate names.
Can I generate a name with no command title, just the plain name?
Yes, and it already happens naturally: 13 of the 31 entries in the title list are empty strings, so roughly 42% of names come out with no "Captain" or any other title, ready for a regular crew member rather than the ship's captain.
