Baby brother for Felix

Hello! We are looking for a name for [name_m]Felix[/name_m]'s baby brother due in a week or so!
[name_m]Hugo[/name_m] was an early fave and is still in the running.
[name_m]Leo[/name_m] is also good, but is it too much to have two cat type names? or maybe we could go with [name_m]Leon[/name_m] instead?

We would like a name that will be easily understood in Europe (as we travel there a lot) but doesn’t seem to pretentious or is overly common.
(We did like [name_m]Oscar[/name_m] and thought we might be able to get away with it until we saw they making a remake of the Odd Couple with [name_m]Matthew[/name_m] [name_u]Perry[/name_u] apparently!)

Thoughts please?

I think [name_m]Felix[/name_m] and [name_m]Hugo[/name_m] go very well together, but here are a few more suggestion:

[name_m]Calvin[/name_m]
[name_m]Lewis[/name_m] (or [name_m]Louis[/name_m])
[name_m]Silas[/name_m]
[name_m]Soren[/name_m]

[name_m]Simon[/name_m]

[name_m]Felix[/name_m] and [name_m]Oliver[/name_m]/[name_m]Olivier[/name_m]
[name_m]Felix[/name_m] and [name_m]Sebastian[/name_m]
