>>12260816This is a tough one amid, you can look to Epona though and find the Romanization of a Celtic Goddess. You will also find a lot of similar/analogous gods to the other Indo-European pantheon.
Where things get dicey is the manner in which the druids were a priest class of pre-Indo European chariot people. The druids came from the west, and were trained in Ireland according to original sources. They would have followed the wheel of the year, written with the Greek alphabet for mundane and legal activity, but it doesn’t appear that the Ogham was part of the continents Celtic experience.
Still, you will find Cernunnos and other common motifs throughout the ancient world.
It also appears that the Gauls had a male God of War in contrast the Island’s Morrigan; so take that for what you will.
