Yes. The Straw Hat Crew, Blackbeard: Marshall D. Teach, the Heart Pirates: Law and Bepo, and one Marco of the former Whitebeard Pirates, are all from my world.
Jack Sparrow and a few others are from other worlds.

I can understand that. There was a case of "supposedly" bounty hunters expanding into a crime ring that involved trying to take over a country in order to get a weapon. And the ring-leader was government acknowledged "hero," a shichibukai -- legalized pirate.

It really doesn't get easier, does it?
