Middle/nickname for William

We are probably going to use [name_m]William[/name_m] as our son’s first name. I’d like something for the middle that is a little bit less common, especially with our fairly ordinary surname. It would also be nice if the middle name or some short form of it could be used as an occasional nickname.

So far we like [name_m]William[/name_m] [name_u]August[/name_u], maybe calling him [name_u]Gus[/name_u] at least when he’s little or in the family. [name_u]August[/name_u] isn’t the smoothest with our last name (starts with S) but it’s not too bad. Other names that I like are [name_m]Arthur[/name_m], [name_m]Caspar[/name_m], [name_u]Beau[/name_u], and [name_m]Julian[/name_m], thought we’d probably go with [name_u]August[/name_u] before any of those particular examples.

Does anyone have suggestions I might not have thought of yet?

[name_m]William[/name_m] [name_u]August[/name_u] nn [name_u]Gus[/name_u] is adorable.
