There's a
Raymond in middle school where I work, and I've only heard him called
Raymond. It's also my dad's name, but his dad was
Ray, so they used his mom's family's tradition of using the middle name instead. He's usually
Tom, sometimes
Tommy (just certain cousins call him that).
I think
Raymond and
Warren work for brothers, but then my mom's brother is
Warren, so I've heard all of the names together all of the time.
