There is no set pantheon worshiped in Wicca. Each tradition honors the God and Goddess by different names. Although I occasionally associate God and Goddess with ancient names, I usually refer to them simply as Lord and Lady.
Often, the God and Goddess are seen as embodying multiple aspects. For the Lady, She is traditionally seen as having three aspects: The Maiden, representing youth, energy, and innocence; The Mother, representing fertility, maturity, and responsibility; and The Crone, representing wisdom, knowledge, and the transition of death.
The Lord can also be represented by three similar aspects. He can be seen as an exuberant youth/Trickster, The Hunter/provider, and the Wise Grandfather.
Personal exploration of the God and Goddess makes up a large part of the journey for a Spiritual seeker. Study the different Gods and Goddesses carefully and the cultures that are associated with them, and you will likely find forms and names that resonate with you.
I would not recommend calling on specific Gods or Goddesses until you’ve really had a chance to get to know them. The various Gods and Goddesses who have been worshiped and honored through the ages are quite specific. You wouldn’t want to inadvertently offend a Spirit of that magnitude through ignorance.
