Centaurs are going to be playing a fairly big role in the upcoming chapter of one of my stories, so I have a few questions that I need cleared up on the subject of the centaurs that reside in the forests around Hogwarts.

Where do the centaur names in the Harry Potter books come from? Has anyone noticed any naming patterns that J.K. has been using in her books?

Does anyone have any theories as to how the Hogwarts centaurs even got there? I believed the originated in Greece, am I right?

I'm sure I will think of more questions to add later, but for now, I will settle for these.
