[name_m]Jasper[/name_m] [name_u]Finn[/name_u] and [name_u]Rowan[/name_u] [name_m]Atlas[/name_m] are my favourites. They are the first names that I prefer as that is how he will be known, but you have a nice list.
Great list. I love; [name_m]Declan[/name_m] [name_m]Elijah[/name_m], [name_u]Rhys[/name_u] [name_m]Arthur[/name_m], [name_u]Rowan[/name_u] [name_m]Atlas[/name_m], [name_m]Cillian[/name_m] (only this spelling) [name_u]Jude[/name_u], [name_m]Jasper[/name_m] [name_u]Finn[/name_u], and [name_m]Liam[/name_m] [name_m]Paul[/name_m]. I also love [name_m]Graham[/name_m] ([name_m]Graham[/name_m] [name_m]Daniel[/name_m]?). My top three would be [name_u]Rowan[/name_u] [name_m]Atlas[/name_m], [name_u]Rhys[/name_u] [name_m]Arthur[/name_m], and [name_m]Declan[/name_m] [name_m]Elijah[/name_m] (the last two tied for second).
I agree that [name_u]Rowan[/name_u] [name_m]Atlas[/name_m] and [name_u]Rhys[/name_u] [name_m]Arthur[/name_m] are standouts. [name_m]Jasper[/name_m] [name_u]Finn[/name_u], [name_m]Killian[/name_m] [name_u]Jude[/name_u], and [name_m]Declan[/name_m] [name_m]Elijah[/name_m] are also great (love the nn [name_m]Dex[/name_m]!) Your [name_m]William[/name_m]/[name_m]Liam[/name_m] and [name_m]Daniel[/name_m] combos are less unique, but just as solid. You really can’t go wrong with anything on your list.
I think they all work really well except that [name_m]Jasper[/name_m] [name_u]Finn[/name_u] and [name_m]Liam[/name_m] [name_m]Paul[/name_m] don’t feel quite as smooth somehow, and I’m not personally fond of either [name_m]Killian[/name_m] (sounds too much like ‘killing’) or [name_m]Atlas[/name_m].
[name_u]Love[/name_u] [name_m]Declan[/name_m] [name_m]Elijah[/name_m] and [name_u]Rhys[/name_u] [name_m]Arthur[/name_m], and [name_m]William[/name_m] [name_m]Paul[/name_m] and [name_m]Daniel[/name_m] [name_m]Graham[/name_m] are nice too (quite ‘sturdy’ names). Really depends on how they flow with the surname.
