Brother or Sister for Leon?

Hello fellow Berries,
Looking for some insight on a good sibling name to go with [name_m]Leon[/name_m], our oldest. At first, we were convinced that it was a boy (and in that case we were juggling Sébastian (Bash), [name_m]Gabriel[/name_m] and everything else in between :D), but now it seems that it might be a girl and we have absolutely no idea. Please share your thoughts/opinions for both boys and girls,would be much appreciated! Thanks!

I think Bash and Leon are really cute together IMO.
