Help me with boys' names that end in s

[fitzbilly]

First name is Max and I want a middle name also ending in an S sound, preferably with more then one syllable.

All I can think of is Atticus but there must be more out there!

Great suggestions everyone, I'll run these past dh.

Ds1 is Felix otherwise we'd use that, it's a great name!

Am strangely drawn to phileas, and love Rufus thank you!

I do love thinking of names!

Shmoo those are some great suggestions, and will think about Leopold!

Cassius
Linus

Erasmus

Seamus

Matthias
