I like Ashby and
Brooks with
Larkin - they both fit well. You could even make a combo like Ashby
Brooks or
Brooks Ashby.
I like
Larkin Elliot,
Tobias,
Joel and
Timothy. I really like a “t” somewhere in the middle name with Larkin...like, I don’t ordinarily pay much attention to
Tobias or
Timothy but they sound good with
Larkin.
