HELP! Need baby names!

I am having a HORRIBLE time coming up with girl names, we are not finding out what we're having so we need both a girls and a boys name. My daughter's name is Hailey, and I love the name Alaina for a girl, except friends of ours just named their daughter that, so that's now off the list. Please help me come up with suggestions!! Perfer something that goes with the middle name Lee (family name) Last name is Rock.

fyi...for a boys name we are thinking either Keegan or Owen...

We are going to name ours Maya Serenity. Ummm others I liked were moira, savannah, kinsley ... crap pregnancy brain won't go away sorry lol

Adella, Abella, Attina.
Coral. Winter. Grace.
Sadie. Alayna. Regina.

Names I had if it was a girl where:
Sophia
Victoria
Aria
Emma
Ava

I really wanted to name my daughter Elaina, but DH hated the name...I was working hard to convince him on it (beings he practically named our boys) and then his best friend from work had a baby girl exactly 1 month before us and thats what they named their daughter, so it was def out.....I ended up with a Emma instead.

Names I liked but couldn't use because either SO didn't like them or it was the name of a friend or family members child are:
Emma
Araceli
Mckenna
Jade

We ended up deciding on Sophia

Laney. Delaney. Ellie. Eden. Emma.

Maverick. Lane. Tanner. Carson.
