I like Bella Luna, Etoile, Heaven, and I add Shasta. she is a beautie.
I have a Farrah, but she is a shetland. My other horse is named Cherokee Angel, beacous I'm part Cherokee and she a part of me, and to me she is an Angel. My dogs name is Kota - friend, I wanted a friend, so that is what I call him. I pick names that mean something to me.
She favors the Arab with her head and neck. If you lived HERE, I'd suggest an Arabic name, but I don't think that would be appropriate. I believe that a horse will adopt the personality of a name. Therefore, I would NEVER name my black horse, "Satan!!!" When I bought my Arab gelding (23 years ago, RIP, June, 2009) he wasn't papered, and DH named him, "Corporal." That's EXACTLY how he acted, too, pushy, brave, obedient, tricky. Your filly reminds me the new moon, dancing. What would that be in Hebrew? THAT is what I'd name her.
BTW, MY nearly black, 3 yr old, 16'2hh and growing, gelding's stable name is "Sweet Cuppin' Cakes."
