Gauri (गौरी) is the Sanskrit word for "fair" or "white" — an epithet of the goddess Parvati, Shiva's consort. In her radiant, golden form.
Gauri Khan (born 1970) is the Indian film producer and wife of Shah Rukh Khan.
Gauri 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 Gauri reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
