So far we have rafferty,[name]Ronan[/name],[name]Russell[/name]
We loved [name]Shea[/name] but it looks as though it has become too girly unfortunately.
Any other offbeat names we will consider,doesn’t have to be r,though I like r names,hubby doesn’t care
I like [name]Ronan[/name] and [name]Rafferty[/name], although [name]Russell[/name] is not my style.
Others:
[name]Roman[/name]
[name]Rex[/name]
[name]Rocco[/name]
[name]Roscoe[/name]
[name]Remus[/name]
[name]Rio[/name]
I [name]LOVE[/name] [name]Rafferty[/name]!
Also like [name]Rhett[/name], which I think is strong and unusual, as well as having a literary reference. [name]Radley[/name] is cool and coincidentally also has a literary reference if you’re at all into that kind of thing 
[name]Reuben[/name]
[name]Regan[/name]
[name]Reynald[/name]
[name]Rhodes[/name]
[name]Rigby[/name]
[name]River[/name]
[name]Riordan[/name]
[name]Roscoe[/name]
[name]Rafferty[/name] is amazing, love it!

[name]Rory[/name]
Rorrick
[name]Roland[/name]
Rozo
Ravelin
[name]Rufus[/name]
[name]Rodney[/name]
[name]Ross[/name]
[name]Love[/name] [name]River[/name], [name]Roscoe[/name], [name]Rowan[/name] and [name]Rory[/name]. I like also like [name]Rogan[/name] and [name]Roderick[/name] (or even [name]Broderick[/name], if you’re not married to the R name idea.) [name]Shea[/name] would make a great middle name for a boy, I don’t think it’s THAT girlie, especially not in the middle spot. You could also use O’[name]Shea[/name] for a middle if you’re feeling super Irish.
[name]Ronan[/name] is my favorite! [name]How[/name] about: [name]Rowan[/name] or [name]Ross[/name]?
[name]Ramsay[/name]
[name]Roarke[/name]
[name]Roman[/name]
[name]Rohan[/name]
Rygiel
[name]Roan[/name]
[name]Rhys[/name] is my sugestion.
[name]Ronan[/name] is my favorite. I would use it in a second if it didn’t clash with our last name.
A non-R name, [name]Conrad[/name], fits the description of what you want pretty well, although it’s not “adorable” necessarily. Strong and adorable is tough!
I like [name]River[/name], [name]Ransom[/name], and [name]Rhett[/name].
The only thing I can think to add that hasn’t been said already is [name]Ren[/name].
[name]How[/name] about [name]Ralph[/name]?
