Well I don't know any personally. I've posted this before, this is what I got out of some of their history..
Wiccan is pagan and is an earth or nature religion, one that sees the divine manifest in all creation. The cycles of nature are their holy days, the earth is their temple, its plants and creatures their partners and teachers. They worship a deity that is both male and female, a mother Goddess and father God, who together created all that is, was, or will be. The attributes of what is even mentioned in scripture with "El" (with an accompanying verb change makes it male or female, otherwise it's neutral)) in respect life, cherish the free will of sentient beings, and accept the sacredness of all creation. Celtic society had gradually spread across Northern Europe into what is now England, France, Germany, Ireland, Netherlands, Scotland etc. They never formed a single political entity, but remained as many tribes who shared a common culture Much of it came from the ancient Celts and Druids and with the persecutions by the Roman, Norman, Saxon invasion along with Christian germicides they had gone underground. Many would confuse them with the worship of many dieties, though I've read its just the Mother Goddess Earth and the Father of light or Sun.
