Names

So my husband and I have been thinking of baby names. Not sure what we are having yet as im only 6 weeks. My MIL has been trying to help also. We want a name that not everyone has. We love the name Kash for a boy and she agrees it's a nice name. But for a girl we thought the name Aiya is pretty and not many people have that name. It's kinda from Game of Thrones. The girls name is Arya, but sounds like Aiya. Well we told my MIL and she is not a fan. She even had the nerve to tell me it's a "black name" and other people agree with her. Wtf. We are not racist as we have interracial family members on both sides of the family. But as we are Caucasian, she seems to think the name is a bad choice. What are your thoughts?
