Constance comes from the Latin constantia, meaning constancy and steadfastness — one of the classic virtue names carried by Norman and medieval noblewomen. It speaks of loyalty, resolve and quiet strength.
Elegant and old-world, it has a timeless dignity, softened by the friendly nickname Connie.
Constance 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 Constance reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
