Pauline is the French feminine of Paul — from the Latin paulus ("small, humble"). National Book Award for Deeper Into Movies (1973).
Pauline 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 Pauline reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
