As Omni said, its something thats helped keep the wiki active. Given the 5 year gap between Bayo1 and Bayo2, speculation and theories are what helped keep the wiki active. Again Most theories come from information supported by the game

The theory that Jeanne is Joan of Arc is supported by the fact that: Hideki Kamiya has gone on record stating that while Bayo is of English descent, Jeanne is of French descent. This, combined with the fact her birthday is the exact same date as the real Joan of Arcs, the fact they share the same name (Janne d'Arc in French, and Joan of Arc in English), strongly supports this.

Her connection to the Umbra Elder is very strong due to the fact she is "Heir" to the clan; she was about to become its next leader after the Umbra Elder. Being the Heir to something means its something you were born into, not something you can earn. So the idea of them being related is strongly supported by the use of the word "Heir". This is a theory supported by the majority, if not all the fans of the Series. The only thing we don't have is confirmation from Hideki him self.
