Clotilde comes from the Frankish hluti (loud, famous) and hild (battle) — meaning "famous in battle." Saint Clotilde (c. 474-545) was the Burgundian princess who converted her husband Clovis I, the first king of the Franks, to Christianity.
Clotilde is widely used in France and Italy.
Clotilde 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 Clotilde reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
