I concur. 1 - the name is French (obviously a nod to Fleur), 2 - Ron and Hermione's kids say that if they married, then Teddy would be their cousin (and Bill is Ron's brother). I don't think it even needs a guess, seems clear.

I thought the end was way too tidy... but as a fan, I looooved it. The one extra thing I would have wanted to know are what jobs they all have.
