My best attempts would be カミラアッナin katakana and　かみらあっな in hiragana, both pronounced exactly the same. I'm not sure if you would ever write it in hiragana, and I'm pretty sure you'd never write it in kanji. Hopefully, a native speaker will come and save the day with better answers.

You are welcome! And I totally agree: getting information from different sources makes learning expirience multidimentional and more real. :)
