I'm having my fifth and last child and its going to be a girl. I have 3 girls already and one boy. They are in order:

Felicity Maya-Winter
Addison Leigh-Jade
Jake Michael-Tyler
Summer Willow-Kate

For my fourth girl, I have a bunch of different names that I like. But because it's my last one its so hard to choose. In my family its a tradition to have two middle names. Mine is Catherine Diane-Ruth. So she'll need to have two middle names. Some names that I like are:

Brooklyn
Macy
Paige
Sarah
Phoebe
Melissa
Skye
Kiana
Hazel
Raine

im up for other suggestions as well!! thanks!!

I love:
Phoebe Sarah-Paige
Kiana Macy-Raine
Melissa Sarah-Raine

I like Brooklyn Phoebe Hazel. They all flow really well.

i like brooklyn hazel-skye

I really like Brooklyn Hazel-Skye. That sounds really good but I still want to look at other options.

Great! Love big families and your names are super! (I have a relation called Felicity and it's made a come-back!)
The hyphenated 2nd names are a lovely idea.
So, okay ... my favourite combination is LYNN-MARIE, it flows so nicely even on its own ... and I'm biased where Scottish is concerned as my partner is a Scot, so:
First my suggestions:
MacKenzie (MAJOR popular but I dunno ...prefer Kenzi on its own)
MacKenzie Lynn-Marie (?)
Kenzi Raine-Marie
Taylor Dayne-Marie (sorry can't resist that singer!)
Tayler Lynn-Marie
Delaney Jay-Lynn
Rebecca Dawn-Lynn
Leilani Rose-Marie (Leilani = 'heavenly flowers' in Hawaiian)
Savannah Skye-Raine (rain on the savannah!)
....or any of yours with Lynn-Marie

Kiana - nice
Brooklyn - too "posh" everyone's copying her, but yes, nice.
Skye - nice
Raine - nice
I left out the ones I don't really like.
(I could've come up with better, this is a rush-job!!)
