As an English name, Abigail first became common after the Protestant Reformation, and it was popular among the Puritans. The biblical Abigail refers to herself as a servant, and beginning in the 17th century the name became a slang term for a servant, especially after the release of the play The Scornful Lady (1616), which featured a character named Abigail. The name went out of fashion at that point, but it was revived in the 20th century.
Due to the popularity of the saint, the name became common in the Christian world during the Middle Ages. The Normans brought it to England, where it was commonly spelled Cecily — the Latinate form Cecilia came into use in the 18th century.
This is one of the few Old English names to be used throughout Europe (in various spellings). A famous bearer was the British composer Edward Elgar (1857-1934). It was also used by author Charlotte Brontë for the character Edward Rochester, the main love interest of the title character in her novel Jane Eyre (1847).
Apart from royalty, this name was only moderately popular in France during the Middle Ages. After the French Revolution, when Louis XVI was guillotined, it became less common.
The Normans brought the name to England, where it was usually spelled Lewis, though the spelling Louis has been more common in America. Famous bearers include French scientist Louis Pasteur (1822-1895), French actor Louis de Funès (1914-1983), Scottish author Robert Louis Stevenson (1850-1894), who wrote Treasure Island and Dr Jekyll and Mr Hyde, and American jazz musician Louis Armstrong (1901-1971).
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.
This name has been borne by two kings of the Franks, two dukes of Normandy, and three kings of Scotland, including Robert the Bruce who restored the independence of Scotland from England in the 14th century. Several saints have also had the name, the earliest known as Saint Rupert, from an Old German variant. The author Robert Browning (1812-1889) and poets Robert Burns (1759-1796) and Robert Frost (1874-1963) are famous literary namesakes. Other bearers include Robert E. Lee (1807-1870), the commander of the Confederate army during the American Civil War, and American actors Robert Redford (1936-), Robert De Niro (1943-) and Robert Downey Jr. (1965-).
