Personally, I don't think Xenovia not having a last name and finding what it is would make an impact.

I think she's just a poor orphan or something like that and the church discovered that she is a natural holy sword wielder and is capable of wielding Durandal, that's why they took her in. Griselda then taught her everything she knows now and that's it.
