Older Brothers are
[name]Easton[/name] [name]Matthew[/name]
Rowdy [name]Paul[/name]
[name]Landon[/name]
[name]Logan[/name]
[name]Luke[/name] not [name]Lucas[/name] please
[name]Layton[/name]
Does not need to be a “L” name so if you have something similar you might want to add i would appreciate it.
Also we have no middle name ideas…
[name]Hi[/name] [name]Paula[/name] [name]Ann[/name]. Out of your choices I would vote for [name]Landon[/name] or [name]Logan[/name], though [name]Landon[/name] would be my first pick as [name]Logan[/name] becomes too popular lately:) As for a fn I´m not quite sure what your looking for there considering your boys names. But I do like the idea of putting the main name as a mn (I understand you call them [name]Matthew[/name] and [name]Paul[/name] or am I wrong?).
We call them [name]Easton[/name] and Rowdy and throw in the middle names when they are in trouble 
I like both of your boys names, [name]Easton[/name] [name]Matthew[/name] and Rowdy [name]Paul[/name]. Great names. To go with such great names I would pick [name]Layton[/name], I think it’s a strong name, but isn’t too popular. Your other sons have names that are known but not very common. Good luck to you!
[name]Easton[/name] has either a cowboy or a preppie vibe, but with brother Rowdy it’s 100% cowboy. I think brother #3 needs the same. Of your choices, only [name]Landon[/name] really has that for me, but I do wonder if it’s too similar to [name]Easton[/name], leaving Rowdy really sticking out.

[name]Bridger[/name]
[name]Dallas[/name]
[name]Ridge[/name]
[name]Waylon[/name]
I would go with [name]Landon[/name] or [name]Logan[/name] from your list. I really like [name]Wyatt[/name] with [name]Easton[/name] and Rowdy.
