I think you have some awesome suggestions already. Tallon is the only one on your list that doesn't seem as common to me. I like it! Who cares about rat poison? Few people will know the brand.

Some others I like:
Otto
Baxter
Banjo
River
Leaf
Ferris
Marvin
Phoenix
Pax
Paxon
Maddox
Orlando
Axel
Dash
Digby
