It's getting more and more difficult to comb through spellings, Mia is currently way more popular than Maya, but Maya has traditionally had more Kreativ spellings. I'm inclined to think that, as names get more popular people tend to find more U-neeq spellings for them so most of the above are probably Mia, but I'm still torn. I also don't think many people actually use the Mae-a pronunciation, the girl I knew was probably an anomaly. Don't even get me started on Karyn/Corin/Corinne!
