Aurore is the French form of Aurora — from the Latin word for "dawn." Aurore Dupin (1804-1876) was the real name of the great French novelist George Sand.
Aurore is widely used in France.
Aurore 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 Aurore reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
