Which surname fits Julian best?

Hey so Ihave a character who’s named [name_u]Julian[/name_u] [name_m]Noakes[/name_m] (nicknamed Jules) and I’ve been thinking of making a blog based on my characters called juliankepler since [name_m]Kepler[/name_m] is his middle name but the idea of [name_m]Kepler[/name_m] being his surname instead came to me and was wondering if I should keep his name as [name_u]Julian[/name_u] [name_m]Kepler[/name_m] [name_m]Noakes[/name_m] or [name_u]Julian[/name_u] [name_m]Kepler[/name_m]? (I’ll just have to find a new middle name)

His original middle name before I started revamping him was [name_u]Oliver[/name_u] and I gave him the middle name [name_m]Kepler[/name_m] since I wanted it to be space-themed since his work is related to space (not sure what his exact job is yet lol) if that’s any help, thanks!

Kepler flows better to me! I trip over Julian Noakes since these two end and begin with the same letter.

I second [name_m]Kepler[/name_m]!
