I really like [name]Nathan[/name] and [name]Nathaniel[/name], though I would switch the middle names and use either [name]Nathaniel[/name] [name]Bryan[/name] or [name]Nathan[/name] [name]Alexander[/name]. I also like [name]Emmett[/name] - have you considered [name]Nathan[/name] [name]Emmett[/name] or [name]Emmett[/name] [name]Nathaniel[/name]?
I think [name]Aiden[/name] and [name]Anthony[/name] are both greatly overused, and I also don’t love the flow of the two together.
Some other names I thought of when I read your list are:
Ephraigm
[name]Gavin[/name]
[name]Aaron[/name]
[name]Benjamin[/name]
[name]Aiden[/name] [name]Anthony[/name]: I think it’s a cool combo, but [name]Aiden[/name] is very, very trendy. It’s part of the meganame trend ([name]Aiden[/name], [name]Jayden[/name], [name]Cayden[/name], [name]Braden[/name], [name]Hayden[/name], etc…), which may or may not bother you.
[name]Nathanial[/name] [name]Alexander[/name]: I [name]LOVE[/name] [name]Nathaniel[/name] (spelled this way), but personally have a hard time saying it with [name]Alexander[/name] due to the L’s in both names.
[name]Nathan[/name] [name]Bryan[/name]: I like [name]Nathan[/name] a lot, but I personally wouldn’t use it with [name]Bryan[/name], as both have two syllables and end in the same sound.
[name]Timothy[/name] [name]Ryan[/name]: I think this has a nice flow, but there are a lot of great Irish names out there in addition to the popular [name]Ryan[/name].
[name]Emmett[/name]: With [name]Emma[/name] being the #1 name for girls, and [name]Emily[/name], the former #1 at #3 now, there are a lot of Ems running around.
From your list, I really love [name]Nathaniel[/name] and [name]Nathan[/name].
