My God and Goddesses names

I read some stuff about being a Heathen on the Pagan forum yesterday and learnt that my Goddess' names are a modernish (12th century) concept.

My Goddesses are who Heathens call Jorg.
My God is who Heathens call Cernunnos.

I remembered Jorg but totally forgot about Cernunnos  :-(

I hope he understood and forgives me for forgetting his name!
