The Little Merman

Writing a story about a guy who sets out on a seafaring adventure to find out who his mother is - all he knows about her is from his deceased father’s coded journal. I need a name for my protagonist. I know the general vibe I want but I can’t find anything that matches - even on name hunter which is rly cool btw. I have names for his friends and parents so I’d like something to balance it out. Problem is that I need a merman-esque name for him bc his mother was a mermaid (and she was the one who named him).

So, here’re the names for the friends who help him on his quest: [name_u]Raye[/name_u], [name_f]Frida[/name_f], [name_m]Dirk[/name_m].
His parents: [name_m]John[/name_m] and Aquaria.

His current name is Trinket, Trink for short but I’m not 100% certain on it.
Vibe I’m going for: [name_u]Orion[/name_u], [name_m]Jupiter[/name_m], [name_f]Lorelai[/name_f].

It has be quite unusual for your generic adventure town ports s everyone comments on how weird his name is. I describe him as being medium height, medium build, dark hair, blue eyes and pale skin (if that hleps). Can I get some help?

I always think of the name [name_u]Marlowe[/name_u] when I imagine beachy/mermaid boys. If that’s not for you here are a few more:

[name_u]Rio[/name_u]
