Confused audiobook listener

In advance, I'd like to say I'm sorry if this question has already been answered somewhere else.

I'm listening to this trilogy on Audible, and I am loving it! The only thing I don't like is trying to guess how names and places are spelled.

I don't know if it's a mistake by the beloved Michael Kramer, or if it's actually written this way in the books...

In the 2nd book, there are 2 occasions where he mentions that Geladra has “her father's notebook” but I thought it was the notebook of Wirr's Father, her late husband?
