Help deciding on names for my little-sister-to-be?

My favorites are Hayden Elizabeth (although I prefer the spelling Elisabeth but both are gorgeous), Arabella Renee (Renee sounds sweeter and flows better with Arabella) and Jacqueline Marie! My favorite is Arabella Renee! I do LOVE the name Elisabeth though, so I would love that as a first name - Elisabeth Summers or Elisabeth Camille! I also would really like Arabella Elizabeth (Elisabeth) or Arabella Summers! Good luck!
