This name was common throughout the English-speaking world for most of the 20th century, though in the 1960s it began a slow decline in most places.
This name was popularized in continental Europe by the works of the 18th-century Scottish poet James Macpherson [1]. Napoleon was an admirer of Macpherson, and he suggested Oscar as the second middle name of his godson, who eventually became king of Sweden as Oscar I. Other notable bearers include the Irish writer and humorist Oscar Wilde (1854-1900) and the Brazilian architect Oscar Niemeyer (1907-2012).
A famous bearer was the American jazz musician Nina Simone (1933-2003).
This name was borne by a 6th-century Byzantine emperor. Another notable bearer was Maurice of Nassau (called Maurits in Dutch), a 17th-century prince of Orange who helped establish the Dutch Republic. The name has been used in England since the Norman Conquest, usually in the spelling Morris or Moris.
This name was very popular in the English-speaking world at the end of the 19th century. Though it declined in use over the next 100 years, it staged a successful comeback at the end of the 20th century. The American sitcom Will and Grace (1998-2006) may have helped, though the name was already strongly rising when it premiered. It was the top name for girls in England and Wales in 2006.
As an English name it was highly popular from the Middle Ages until the 17th century. It was revived in the 19th century and was common into the 20th, but it fell into decline after the 1930s. It last appeared on the American top 1000 rankings in 1972.
