Names?

My hubby and I have 2 girls, Rylee Anne and Bailey James, and are expecting #3 in July. We have been talking about names and he really wants Mason Rexford (after his grandpa) if its a boy and doesn't want to talk about girls names bc he is really hope this is a boy LOL. Im kinda liking Makenna for a girl, but can't fully decide on a middle name. I thought maybe Makenna Lynn (Lynn is my middle name) or maybe Makenna Rae. I like shorter middle names with Makenna. Anyone have any thoughts or other suggestions?

Thanks!!
