I've known plenty of people named
Trey (as a given name) and I always thought it seemed insubstantial. The knowledge that it was initially used as a nickname makes a great deal of sense to me.
I really like
Ambrose.
I think the combination doesn't make a whole lot of sense, but at the same time I wouldn't hate seeing it be used.
