Christine is the French feminine of Christian — from the Greek christianos (follower of Christ). Christine de Pizan (1364-1430) — Italian-French author whose The Book of the City of Ladies (1405) is among the earliest works of feminist literature in European history.
Subject of countless ECB and IMF profiles.
Christine 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 Christine reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
