Here's the deal:
My mom loves to come up with ridiculous nicknames, and has to nickname all of her kids. My poor niece Sophie was called Doff for quite some time (despite the fact that it means stupid in German.) Because of this I want to be prepared for whatever she comes up with and to offer "alternatives."
So here are the names:
Joss -Jossy is probably inevitiable.
Cecilia
Margaret
Mariana
Thaddeus
Thanks!
