Sir Richard Ratcliffe

I'd like to add Richard's right hand man to my cards, but I'm having
difficulty finding details.
I need to know where Ratcliffe's principle estate was, and a
description of his coat of arms.
Was he related to the Radcliffes, Lords FitzWalter? I believe a branch
of this family were created Earls of Derwentwater (Westmoreland), and I
believe this is where Richard originally hailed from, so I assume there
is some connection.
