Congrats on expecting...I am with @Hairless Blessing give us a theme or things you are in to so we can share ideas. I see you are getting an Elf....try googling female elf names...there are many cool ones that come up.
@Mariah Joubert Just like you said, it will come to you. Of all of our cats only one we struggled with. The others we had their name before they came home to us. You really do have a great list going. You will find that you will have fun names you call them based on the name you choose...lol. It happens naturally. Have fun.
