Interestingly, with this sounding like a somewhat realistic Norwegian/Danish name, it should actually show up at the bottom by the sorting rules of those two languages.
The digraph "aa" is an archaic representation of the modern character "å", the last letter of the Norwegian and Danish alphabets, and should be sorted accordingly.
