This was the name of a 13th-century Italian saint who made clothes for the poor. As an English name, it has never been common.
The name was borne by a semi-legendary 4th-century saint and martyr from Alexandria who was tortured on a spiked wheel. The saint was initially venerated in Syria, and returning crusaders introduced the name to Western Europe. It has been common in England since the 12th century in many different spellings, with Katherine and Catherine becoming standard in the later Middle Ages. To this day both spellings are regularly used in the English-speaking world. In the United States the spelling Katherine has been more popular since 1973.
Famous bearers of the name include Catherine of Siena, a 14th-century mystic, and Catherine de' Medici, a 16th-century French queen. It was also borne by three of Henry VIII's wives, including Katherine of Aragon, and by two empresses of Russia, including Catherine the Great.
The name was popular in France during the Middle Ages (the more common French form is Gisèle). Though it became known in the English-speaking world due to Adolphe Adam's ballet Giselle (1841), it was not regularly used until the 20th century.
