Désirée is the French past participle of désirer ("to desire") — "the desired one." Désirée Clary (1777-1860) was Napoleon Bonaparte's first love — they were engaged before he met Joséphine. She later married Napoleon's general Bernadotte, who in a remarkable twist of fate was elected King of Sweden, making Désirée the Queen of Sweden and Norway as Desideria, founding the modern Swedish royal house.
Subject of Annemarie Selinko's novel Désirée (1951) and the 1954 Hollywood film starring Jean Simmons.
Désirée 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 Désirée reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
