First off, [name_m]Boston[/name_m] and [name_u]Hollis[/name_u] sound SO cool for siblings. Very dapper but also masculine as well! I think from your list, [name_u]River[/name_u] and [name_m]Jones[/name_m] work really well. Both have the same unique feel while still being masculine, and they feel like a natural addition.
I personally LOVE the name [name_u]Jonah[/name_u] and quite like [name_u]Julian[/name_u] and [name_u]James[/name_u]/Jamie. All are strong and handsome names that I think wear well at any age and retain masculinity while also being a little softer. While I think [name_m]Boston[/name_m] and [name_u]Hollis[/name_u] share this quality, they seem a little too unique to go with more traditional names like these. I’m fairly indifferent about [name_m]Cyrus[/name_m]/Cy, but for your set, I think it clashes a little with [name_u]Hollis[/name_u]. I just don’t think any of them work as well as [name_u]River[/name_u] or [name_m]Jones[/name_m]!
Some other suggestions (apologies for any repeats):
[name_u]Ash[/name_u]
[name_u]Beckett[/name_u]/Beck
[name_u]Brooks[/name_u]*

[name_u]Flynn[/name_u]
[name_m]Foster[/name_m]*
[name_m]Graham[/name_m]*
[name_m]Grant[/name_m]
[name_u]Gray[/name_u]*
[name_m]Harrison[/name_m]*
[name_m]Langston[/name_m]

[name_m]Thatcher[/name_m]

[name_u]Wilder[/name_u]*
I marked all the ones I really like with an asterisk. The ones that really stand out to me though are [name_m]Foster[/name_m], [name_u]Gray[/name_u], [name_m]Harrison[/name_m], [name_m]Piers[/name_m] and [name_u]Wilder[/name_u]. I think they all complement really well and offer something different to add to your sibset, depending on what you’re going for.
Boston, [name_u]Hollis[/name_u], and [name_m]Foster[/name_m]
[name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_u]Gray[/name_u]
[name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Harrison[/name_m]
[name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Piers[/name_m]
[name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_u]Wilder[/name_u]
My personal favorite is definitely [name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Foster[/name_m]. I think it’s so perfectly balanced and has all the right sounds and styles while still having three distinctly different names. [name_m]Foster[/name_m] just fits flawlessly with your other boys! [name_f]My[/name_f] runner up is [name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Harrison[/name_m], as I think it just rolls off the tongue. [name_m]Harrison[/name_m] is almost like the perfect mashup of [name_m]Boston[/name_m] and [name_u]Hollis[/name_u] while still being totally unique. Taking third is [name_u]Wilder[/name_u]. It’s so offbeat and different but not quite popular yet. It’s the perfect time to jump on in.
So in order:
- Foster - [name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Foster[/name_m]
- Harrison - [name_m]Boston[/name_m], [name_u]Hollis[/name_u], and [name_m]Harrison[/name_m]
- Boston, [name_u]Hollis[/name_u], and [name_u]Wilder[/name_u]
No matter what you choose, you’ve got a solid set of boy names that are all really great! I know whatever you decide will be just right for you. Best of luck!
