1.) Brigit, Brigid or Bríg (/ˈbrɪ.dʒɪd/, /ˈbriː.ɪd/, "exalted one") was a goddess of pre-Christian Ireland. She appears in Irish mythology as a member of the Tuatha Dé Danann, the daughter of the Dagda and wife of Bres, with whom she had a son named Ruadán.
It has been suggested that Brigid is a continuation of the Indo-European dawn goddess. She is associated with the spring season, fertility, healing, poetry and smithcraft. Cormac's Glossary, written in the 10th century by Christian monks, says that Brigid was "the goddess whom poets adored" and that she had two sisters: Brigid the healer and Brigid the smith. This suggests she may have been a triple deity.
Saint Brigid shares many of the goddess's attributes and her feast day was originally a pagan festival (Imbolc) marking the beginning of spring. It has thus been argued that the saint is a Christianization of the goddess.Brigid in Wikipedia
