First name + Middle name combinations. HELP

What are your thoughts on these names?

[name_f]Mia[/name_f] [name_f]Rosalyn[/name_f] - (does [name_f]Rosalyn[/name_f] flow well?)
Gracyn [name_f]Ava[/name_f] “[name_f]Gracie[/name_f]”
[name_f]Abrielle[/name_f] [name_f]Grace[/name_f]
[name_u]Emery[/name_u] [name_f]Rose[/name_f]
[name_u]Addison[/name_u] [name_f]Claire[/name_f]

[name_m]Colton[/name_m] [name_u]James[/name_u] “[name_m]Colt[/name_m]”
[name_m]Jackson[/name_m] [name_u]Reese[/name_u]
[name_u]Finn[/name_u] [name_m]Jacob[/name_m]
[name_u]Brennan[/name_u] [name_m]Mark[/name_m]
[name_m]Ezra[/name_m] [name_m]Matthew[/name_m]

Which ones are your favorites & what do you think of the first + middle name combinations??

They all sound nice. I depends on the the last name too.

[name_m]How[/name_m] do you say Gracyn? Is it meant to be [name_f]Gracelyn[/name_f]?

I thought about [name_f]Gracelynn[/name_f] at first but it just didn’t click with me. I pronounce Gracyn - like [name_f]Grace[/name_f] with a N at the end (If that makes any sense!)
