Help with baby names!!

So our last night is [name]Mata[/name] and we are having a tough time finding first and middles names that flow well with it… We are having twins a boy and a girl:) We have some names in in mind, but if you have any suggestions i would love to hear them.
So for girls we were thinking…
Everleigh
[name]Helena[/name]
[name]Fiona[/name]
[name]Seraphina[/name]

And for boys we were thinking…
[name]Tristian[/name]
[name]Wyatt[/name]
[name]Hayden[/name]
[name]Kellan[/name]
[name]Gavin[/name]

If you could helps with middle name to go with them that would be great
Thanks [name]Kaia[/name]
