Yes. After all, she works at the Polestar Preschool. I don't know where that guy got the idea that Paula's last name was Jones.

No it's not. I hate it when people say it is, it screams ignorance. Whoever made that her name on Nintendo Wikia didn't do research. Never in anything is it ever stated that Paula's last name is Polestar. The "Polestar" in the preschool's name is in fact a pun on her name, going by Japanese. Paula's name is spelled ポーラ (Pōra), while Polestar is spelled ポーラスター (Pōrasutaa). They share the first three katakana. Therefore, it's a pun, and therefore, it's unlikely that would be her last name. Her parents evidently named Paula after the preschool, or alternatively the preschool was named after Paula.

Furthermore, it was some kind of obscure material that stated that her last name is Jones. I can't say if that is canon or not, but it sure as heck is more valid than "Polestar" will ever be.

I don't care what anyone says, because it isn't said in official material, Polestar is not Paula's last name, unless Itoi comes out and says it is, which he won't.

Do you know where it was stated that Paula's last name was Jones?

I renamed that page on Nintendo Wiki just now since the claim "Paula Polestar" as her full name is false

I looked more into it, I had known that Paula's last name was said to be Jones in something obscure, but didn't remember what, and also didn't remember if it was canon.

Quoting Kenisu - "The official MOTHER 2 manga by Benimaru Itoh refers to Paula’s house as the ジョーンズ家 (the “Jones residence”) at the top of page 8 (I could have sworn I had a scan somewhere around here…). I don’t know if it’s this manga that this whole “Paula Jones” thing started from, or if it’s stated in some official guidebook or what…"

Quoting Linkdude20002001 - "The Nintendo Official Guidebook states her name is Pola Jones (ポーラ・ジョーンズ) and that she is 11-years-old. Her father’s name is Paul Jones (ポール・ジョーンズ), and they live in Polestar Pre-school (ポーラスター幼稚園)."

Since the manga is official, and so is the Nintendo Official Guidebook, I think it's safe to say that Paula's last name cannotically is Jones. Also, her father's name is Paul. Who knew?

I thought everyone knew that

Sorry, I didn't know that.

What? No.@DankRat666 Her name is Paula Jones
