5th Help ID pottery/ceramics? Who is RAY?

[2rubeus2]

Very nice heavy smooth stoneware creamer with impressed RAY stamp. It looked like Ray Marshall's work, but that is not his mark.

So, who is "RAY" ??

Perhaps RAY is initials?

Yes, I have considered that, but then, who is R.A.Y.?

Thanks for reply.
