First name for middle name Louis

We just found out we’re having a boy! But…. we have no boy names we’ve agreed on. We know his middle name is Louis, after my dad. What are your ideas for first names that go with Louis?

A few guidelines:

1) Our last name is Smith, so obviously there are some VERY common first names we want to avoid. We don’t need more John Smiths…

2) We like traditional/old-fashioned/romantic names (our favorite girl names were Charlotte and Alice)

3) I have a strong opposition to names based on seasons, months, or places.

Bonus) I am ethnically Filipino/German, and my husband has roots in Great Britain and Ireland. I would love a name with those roots, but it’s not a deal breaker if not.

Thanks in advance!
