[name]Easton[/name] [name]Matthew[/name]
Rowdy [name]Paul[/name]
Our last name starts with a “M” and is very common.
[name]Baby[/name] [name]Sister[/name] ?
If you have another suggestion that you think would fit well with our boys please let me know.
Thank you
I think of your choices [name]Summer[/name] works the best. [name]Charlotte[/name] would be second, but it’s lost a lot of it’s spunk to me with it’s popularity.
[name]Summer[/name] is my favourite from your list, but I think [name]Mackenzie[/name] goes best with your boys. If you do choose [name]Mackenzie[/name] my prefered spelling for it is either [name]McKenzie[/name] or [name]MacKenzie[/name] 
I think [name]Adalyn[/name] goes best! [name]Easton[/name] and Rowdy are so uncommon, you need a somewhat uncommon name to go with them, not a supper common one like [name]Charlotte[/name]. Although, I also love [name]Summer[/name] and think it works too! I disagree with the poster above, if you go with [name]Mackenzie[/name], I like your spelling, not the capital K spelling. Also, having a common M last name, I wouldn’t use a first name that starts with M, or a super common fn like [name]Charlotte[/name]. [name]Callie[/name] is ok, but feels incomplete to me. [name]Easton[/name], Rowdy, and [name]Adalyn[/name]! They sound great! And [name]Addie[/name] is an adorably nickname!
[name]Summer[/name] would be my first choice. [name]MacKenzie[/name] too fits well with your boys; it just depends how you feel about first and last names both starting with M.
I think [name]Mackenzie[/name] probably fits the best but I’m not a fan!! I love [name]Summer[/name] and it goes really well with your boys too… [name]Adalyn[/name] also sounds great and fits nicely!
