For the first level of the christmas wonder, what is the full name of the neighbour for the typewriter?

Daisy Anya Parker

Daisy Anya Parker.

If you compare the border of the letter with the borders on the envelopes, there are two that are the same. One of them has green stars drawn on it like the letter, which is the letter from Daisy. If you look at the letter with the code name and exclude the letters that spell ‘Daisy’, you’re left with four letters that spell the name ‘Anya’.
