Brigid (Old Irish Bríg) means "exalted one." The pre-Christian Irish goddess of poetry, smithcraft, healing, and sacred fire — daughter of the Dagda, of the Tuatha Dé Danann. Her cult was so beloved that the Christian church absorbed her as Saint Brigid of Kildare (c. 451-525), second patron of Ireland after Saint Patrick. The eternal sacred flame at her shrine in Kildare burned for over 1,000 years, tended by a sisterhood of 19 nuns, until extinguished by Henry VIII; it was relit in 1993.
Brigid does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Brigid reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
