After some help from you all, we have narrowed down [name_m]Henry[/name_m]'s future brother’s name.
[name_m]Henry[/name_m] and [name_m]Maxwell[/name_m] (most likely nn [name_u]Max[/name_u], of course) b
[name_m]Henry[/name_m] and [name_m]Oliver[/name_m] (nn [name_u]Ollie[/name_u])
or
[name_m]Henry[/name_m] and [name_m]Theodore[/name_m] (nn [name_u]Theo[/name_u])
Thoughts?
Thanks 
I really like both [name_m]Henry[/name_m] and [name_m]Oliver[/name_m] and [name_m]Henry[/name_m] and [name_m]Theodore[/name_m]. [name_m]Oliver[/name_m] and [name_m]Theodore[/name_m] are stylistically similar to [name_m]Henry[/name_m], giving the sibset a wow factor. I would love to meat either sibset! My vote goes to [name_m]Theodore[/name_m] though because personally I just like him better than [name_m]Oliver[/name_m].
[name_u]Theo[/name_u] and [name_u]Max[/name_u] are great names (they sound pretty good together too, no?), but my favorite pairing is [name_m]Henry[/name_m] and [name_m]Oliver[/name_m] (nn [name_u]Ollie[/name_u]).
[name_m]Oliver[/name_m] gets my vote for a brother to [name_m]Henry[/name_m], with [name_m]Theodore[/name_m] being my second pick.
I like [name_m]Henry[/name_m] and [name_m]Oliver[/name_m] the best, but I really like all your choices!
All your choices work well with [name_m]Henry[/name_m] but I adore [name_m]Henry[/name_m] and [name_m]Oliver[/name_m]. Such a handsome and sweet set.
1 [name_m]Henry[/name_m] and [name_m]Oliver[/name_m]
2 [name_m]Henry[/name_m] and [name_m]Theodore[/name_m]
3 [name_m]Henry[/name_m] and [name_m]Maxwell[/name_m]
[name_f]Love[/name_f] all 3! With [name_m]Henry[/name_m], I prefer [name_m]Theodore[/name_m] ([name_u]Theo[/name_u]), & [name_m]Oliver[/name_m]. [name_m]Both[/name_m] are great so I really can’t decide between them sorry. Might come down to which goes best with your last name & mn. GL
[name_m]Henry[/name_m] and [name_m]Maxwell[/name_m]. I know I’m in the minority here, but if you consider nn and all, [name_m]Henry[/name_m] & [name_u]Max[/name_u] sounds better than [name_u]Ollie[/name_u] or [name_u]Theo[/name_u]. All good names though. Great picks!
[name_m]Henry[/name_m] is getting more common, but it is such a pleasing solid name.
I like [name_m]Henry[/name_m] [name_m]Oliver[/name_m] best or [name_m]Oliver[/name_m] [name_m]Henry[/name_m].
[name_m]Theodore[/name_m] is my #1
[name_m]Henry[/name_m] and [name_u]Theo[/name_u] is so cute.
Another vote for [name_m]Oliver[/name_m] here!
