I definitely think [name_m]Neville[/name_m] is usable.
I forgot about this thread! Thanks everyone for your opinions. I’ve officially added [name_m]Neville[/name_m] to my list for middles. Now I just have to figure out what first name I would pair it with it. 
I like [name_m]Neville[/name_m] a lot, but I do have a thing for nerdy names ([name_m]Gilbert[/name_m], [name_m]Ernest[/name_m] etc…). If you did want to use it for a first name, Noddy Holder’s real name is [name_m]Neville[/name_m], so you could use Noddy for a nn, which I think is adorable, especially on a little one! x
I much prefer it as a middle name. [name_m]Neville[/name_m] doesn’t really complement my other favorites, but I think it goes great with my middles.
