Help! Need a name for our first daughter

We are expecting our third child.....a GIRL! Help us settle on a name as we are torn between four possibilities. Middle name options would be helpful too. Big brothers are Braden and Carter. We'd like a girl's name that flows with theirs. Additional name ideas are welcome!
  1. AdelynHeart
    • Origin:

      Variation of Adeline
    • Meaning:

      "noble, nobility"
    • Description:

      Adeline in all its forms, including Adelyn, is rocketing up the list, but we do prefer the original to the variations. Or you might consider varying it yet further to Adelia, Adele, or Adelaide. Or lengthen it to Madeline/Madelyn.
  2. ElsieHeart
    • Origin:

      Diminutive of Elizabeth via its Scottish variation, Elspeth
    • Meaning:

      "pledged to God"
    • Description:

      Elsie is a sweet vintage nickname-name turned modern star. After a 30-year hiatus, Elsie started climbing the US popularity list 20 years ago and is still headed for the top.
  3. HarperHeart
    • Origin:

      English
    • Meaning:

      "harp player"
    • Description:

      You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.
  4. SadieHeart
    • Origin:

      Diminutive of Sarah
    • Meaning:

      "princess"
    • Description:

      Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.
