Is
Raya pronounced like RAY-a or Rah-ya? Since I think it could be pronounced either way, I'm going to downvote it.
Raina /
Rayna is a bit clearer.
Iris is willowy and genteel but not very robust sounding- like a woman given to fainting spells in an old movie.
Wren has cottagecore cuteness but is a bit too twee for my taste.
