Meaning and history
Giselle comes from the Old German element gisal, meaning “hostage” or “pledge” (Proto-Germanic *gīslaz), and may originally have been a descriptive nickname for a child given as a pledge to a foreign court. It was borne by a sister and a daughter of Charlemagne, a daughter of the French king Charles III who married the Norman leader Rollo in the 10th century, and Gisela of Swabia, wife of the Holy Roman emperor Conrad II. Popular in medieval France in the form Gisèle, the name became familiar in the English-speaking world through Adolphe Adam’s ballet Giselle (1841) but was not widely used there until the 20th century.
Giselle moved from #358 to #382 for girls between 2024 and 2025. Its highest annual birth count came in 2007, with 2,596 births.
