Bridgette is a French-influenced spelling of Bridget — from the Irish Brighid ("exalted one, strength"), the name of both the Celtic goddess of poetry and the most-revered Irish saint after Patrick.
and American pop culture.
Bridgette 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 Bridgette reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
