That’s a post I wanted to create for months (since season 6 episode 7 in fact).

Jaune is knowned for having a large familly (and having ancestors who fought in the Great War). But where are they from ? For long I thought they were from Vale like most of the students at Beacon Academy (and even if it became more of an exception for the two main quartets members, Blake, Weiss, Pyrrha, Ren and Nora being not natives). But in the episode where his sister is introduced, Saphron answered Blake if she was the only Arc living here : « Yes, moved the second I could. Jaune and I are the only two living away from home. » 

And so ?

First and certain deduction that could be made is they’re not from places Jaune and Saphron lived (Vale and Argus). Arc’s familly being humans they’re also not from Menagerie.

What place are still possible ? :

- Atlas / Mantle

- Vacuo

- Mistral

- Somewhere else we still don’t know

Well cause of certain minor details I’ve gathered, my guess goes to Atlas / Mantle. If anyone has other elements that accord, or not, with this hypothesis, feel free to explain. ;)

- First Jaune knows Weiss as a talented singer (season 2 chapter 6 around 4:40 Jaune speaks to Ren about Weiss : " She's cold, but... she's also incredible. She's smart and gracefull and talented, I mean, have you heard her sing ? ") , but in the show she is not showed being singing at all. She should have done so offsreen of course and this is far from being an irrefutable argument. But Jaune could have witness one (or more) of her performance cause he came from the same place (he also didn’t attempted a combat school where Weiss could recognize him from).

- Also, Jaune seems proficient in the history of Agus development (which occured with the help of Mantle) and in my own sense it’s seems he show some pride telling this story (it happens in the tramway ep 7 season 6). It’s a weak argument (he could have learn from Saphron) and I wouldn’t have considered it without other clues.

- Finally, Jaune has a name coming from french langage and no one else. We know two other characters with such a trait : Ciel Soleil and Jacques Gelé (not Jack, Jacob or anything : Jacques as in Jacques Chirac -french president from 1995 to 2007- and a previous name also coming from french, accent included). I’m quite sure no other character has such a caracteristic, being french myself it’s something I would have spotted. But I can’t be adamant on this, please correct if I’m wrong. Ciel and Jacques come from Atlas. Even Arc could be from french (arc meaning bow… like the two he ‘s got as symbol). One counter argument is Saphron, if she would have a french origine name she would called herself Safran.

It’s also possible Arc Familly is from Vacuo. I  haven't read much from After the Fall, but in my own sense, Jaune doesn’t seems to feet with the region especially in his begining. There maybe elements from the book I don’t know. If you have please develop. But it’s possible we will have further elements that go in this way.

It’s unlikely Arc familly is from Mistral., because it’s unlikely the group would go back there. And for me Jaune’s other six sisters are obvious Tchekov gunswomen. And if Jaune is from Mistral I think he would have known Pyrrha better than a cereal mascot (she’s pretty famous there, certainly not as much as in Argus, but still).

Let see your aguments and guesses and we would see the possible implication latter ;).
