[name_m]Atticus[/name_m] and [name_m]Linus[/name_m] are my favs from your new list!
[name_m]Linus[/name_m] [name_m]Edmund[/name_m]
[name_m]Silas[/name_m] [name_m]William[/name_m]
[name_u]Lionel[/name_u] [name_m]Judah[/name_m]
[name_m]Sebastian[/name_m] [name_u]Jude[/name_u]
The only one I really like from the remaining list with [name_m]Caspar[/name_m] and [name_m]Felix[/name_m] is [name_m]Atticus[/name_m].
I don’t find [name_m]Rufus[/name_m], [name_m]Otto[/name_m] or [name_m]Rocco[/name_m] to fit in nicely. [name_m]Quentin[/name_m] and [name_m]Linus[/name_m] would be nice, especially the latter would give the sibset a very European vibe.
Hmm…
I think [name_m]Casper[/name_m] is quiet a hard name to pair up with, it’s quirky and predominantly traditional in Netherlands and Scandinavia, therefore I feel struggles to work with many English sounding choices like [name_m]William[/name_m] or [name_u]James[/name_u]. However I think [name_m]Casper[/name_m] works well with [name_m]Felix[/name_m] as they both have a fashionable quality.
From your list I think [name_m]Casper[/name_m] works with [name_m]Lincoln[/name_m], [name_m]Otto[/name_m] & [name_m]Hugo[/name_m] the best as they have the same fashionable quality of [name_m]Casper[/name_m] and still sound good and predictable with [name_m]Felix[/name_m]. All three are lovely but [name_m]Lincoln[/name_m], [name_m]Casper[/name_m] & [name_m]Felix[/name_m] sound swell together : )
My favourite combinations for your twins would be [name_m]Casper[/name_m] [name_m]Edward[/name_m] & [name_m]Lincoln[/name_m] [name_u]Jude[/name_u]!!
