J.K. Rowling revealed that Fantastic Beasts and Where to Find Them's two female leads, Porpentina and Queenie (played by Katherine Waterston and Alison Sudol, respectively), have the last name Goldstein.

And for those wondering, yes, they are distantly related to Harry Potter's Ravenclaw classmate Anthony Goldstein.

Well, I think it's widely known that that characters of (Porpen)tina and Queenie are sisters, but not that their surname is Goldstein.
