Here are my thoughts on the boys:
Everett-This is totally perfect w/Roland. It has the same dapper sharp slightly vintage vibe. It’s a bit popular though, if that bothers you.
Jameson-This is nice too. I like this spelling as well. And the nn [name_u]Jem[/name_u]. It also seems like a great fit w/Roland. Polished & smart & a little bit outdoorsy. Not quite as common as [name_u]Everett[/name_u], but well known. You may get an occasional [name_u]Jamie[/name_u], so hopefully you don’t hate that.
Gideon-Another nice choice. I don’t like it quite as much as some of the others. It just sounds a little bit too stuffy geeky. Like [name_u]Sheldon[/name_u] on Big Bang [name_u]Theory[/name_u]! But some days I think it sounds clever & sweet.
Jasper-I can’t get into this one either. It reminds me of the word jester, so it feels goofy. Most people seem to love it.
Thaddeus-This is nice. Similar vibe as [name_m]Roland[/name_m]. Fairly uncommon but not overly complicated. Lots of great nns like [name_m]Thad[/name_m], [name_m]Tad[/name_m], [name_m]Thatch[/name_m], Thax & [name_u]Teddy[/name_u]. I like [name_m]Thatch[/name_m] best w/Roland.
Tobias-Not a bad name at all. [name_m]Just[/name_m] not my personal favorite. I think it’s the ‘toe’ part. But it’s a good solid name. Not too popular but not too out there. Has a slightly nature-y yet smart & down to earth vibe.
Emmett-Pretty cute. I like it more in theory than the actual sound. But it’s a nice name that goes well w/Roland.
Theodore-I adore this name. It’s getting popular, but I guess for a good reason. It’s smart & charming & classic.
Atticus-I like this one a lot. It has a similar vibe to [name_m]Roland[/name_m] too. It has a vintage yet fresh feeling at the same time.
Sebastian-A bit more popular than some of the others, but probably my favorite in general. So handsome & lovable. Really nice w/Roland. I like the nns for it as well. Like [name_m]Satch[/name_m], [name_m]Seb[/name_m], Sebby & Bash.

Hope this helps.
