There was no set religion or deities for the druids as Celtic druidism was never a unified religion.

What is certain is that no matter what the names or faces that these gods or goddesses had, they all represented a different part of nature from the perspective of the Celtic people. The druidic religions were all very compatible and a sea god in the western part of England would just be taken as another name for the eastern Celtic druids gods.
