Bridget (Brigid, Bride, Bridey) of Kildare was born around 450 into a Druid family, being the daughter of Dubhthach, court poet to King Loeghaire. At an early age, she decided to become a Christian, and she eventually took vows as a nun. Together with a group of other women, she established a nunnery at Kildare. She was later joined by a community of monks led by Conlaed. Kildare had formerly been a pagan shrine where a sacred fire was kept perpetually burning.
Rather than stamping out this pagan flame, Bridget and her nuns kept it burning as a Christian symbol. (This was in keeping with the general process whereby Druidism in Ireland gave way to Christianity with very little opposition, the Druids for the most part saying that their own beliefs were a partial and tentative insight into the nature of God, and that they recognized in Christianity what they had been looking for.) As an abbess, Bridget participated in several Irish councils, and her influence on the policies of the Church in Ireland was considerable.
Many stories of her younger days deal with her generosity toward the needy.
