Ok, I need GIRL💕🎀💕 names!

Amanda • Wife to my best friend❤️2/3/11. Mommy to two beautiful boys💕2/25/11 && 8/2/13. Mommy to three Angel Babies👼🏼👼🏼👼🏼
I was thoroughly convinced that baby #3 would be a boy as well and now I'm in shock and We can't agree on a name!!!! We want to use my husbands late grandmothers name as her middle so it would be
 ********* Joy Cobb so we were looking for longer first names. (Not opposed to two middle names)  We just can't decide! Which really stinks because I want to do monograms and lettering on a few things in her room. But without a name I'm at a loss! HELP.
