It’s perfectly correct. There are two people named Trevor.

So the plural is named Trevors.

Are you trying to suggest the correct plural of named Trevors is Trevi?

They’re named Trevi is completely wrong.

What? If you saw them walking down the street together would you say

There go the Trevors

Or there go the Trevor?

They’re named Trevors

It’s clearly plural

A lot of posts but no-one has yet to say.

They’re named Trevors

Clears the whole thing up.

Those are some weird as fuck looking children.
