It has occasionally been used as an English given name since the 16th century. It was moderately popular in the 1940s, but had a more notable upswing in the early 2000s. This may have been inspired by the Spanish actress Penélope Cruz (1974-), who gained prominence in English-language movies at that time. It was already rapidly rising when celebrities Kourtney Kardashian and Scott Disick gave it to their baby daughter in 2012.
As a given name for girls, it received some public attention from a character in the 1958 novel Parrish and the 1961 movie adaptation [1]. It experienced a larger surge in popularity in the 1980s, probably due to the character Paige Matheson from the American soap opera Knots Landing.
A notable bearer of this name was Marie Antoinette, a queen of France who was executed by guillotine during the French Revolution. Another was Marie Curie (1867-1934), a physicist and chemist who studied radioactivity with her husband Pierre.
In France it is occasionally used as a masculine name in pairings such as Jean-Marie.
There was a medieval English form of this name, Helewis, though it died out after the 13th century. In the 19th century it was revived in the English-speaking world in the form Eloise.
In the Middle Ages this name was common in England due to the popularity of medieval tales about the Trojan War. It subsequently became rare, but was revived in the 20th century.
