Brother to Leighton & Sebastian! Needs a name!

Hello Berries,
Since I frequent this site often, this is for my cousin who is expecting her third child & 2nd boy this fall. I cannot seem to be of much assistance to her since I can’t really pinpoint her style and she has only a few ideas for names but needs & would like more suggestions. Any help would be greatly appreciated!
Her kids are: [name]Leighton[/name] [name]Olivia[/name] & [name]Sebastian[/name] [name]Rhys[/name]

The only ideas she has for her boy are:
Kirkland
[name]Barnaby[/name]
[name]Evander[/name]
[name]Malcolm[/name]
[name]Abbott[/name]
[name]Forrest[/name]

Any ideas for her? Thanks!
