It is the first name of Vibia Perpetua, a pre catholic saint and martyr who is one of the “They were Roommates” historical figures. amedievalwomanscompanion.com/perpetua/
She is considered a saint of the sapphics and trans people, because she saw herself as a man in a dream.
BTW I’m not religious at all, it sounds great, starts with a V and the story is cool.
