dnd 5e – What are other names for characters of the Arthurian legend?

I work on a homebrewish world and have always thought that the legends of King Arthur and the Knights of the Round Table were cool. I intended to found one of my kingdoms on it, but did not want to immediately realize that the characters came from the legends. I'm looking for alternate names that could point to all the main characters and locations, like Arthur, Merlin, Morgana, Lancelot, Mordred, Guinevere, Camelot, etc.
