I have never met a
Raymond IRL.
My first association is Captain
Raymond Holt from
Brooklyn 99, who is an African American and a wonderful character on the TV show.
I do think
Raymond is very dignified, but also friendly.
Ray for me works as a nickname and a full name in its own right. Very friendly and reliable.
Myron sounds awkward and nerdy. I have no associations with it at all but I can't imagine it on a young man. Although I imagine most
Raymond's are older, I can easily picture a young
Ray.
