This name was initially more common among Eastern Christians in the Byzantine Empire, but it flourished in Western Europe after the First Crusade. In England it became extremely popular, typically being the most common male name from the 13th to the 20th century (but sometimes outpaced by William). During the later Middle Ages it was given to approximately a fifth of all English boys. In the United States it was the most common name for boys until 1923.
The name (in various spellings) has been borne by 21 popes and eight Byzantine emperors, as well as rulers of England, France, Sweden, Denmark, Poland, Portugal, Bulgaria, Russia and Hungary. It was also borne by the poet John Milton (1608-1674), philosopher John Locke (1632-1704), American founding father and president John Adams (1735-1826), and poet John Keats (1795-1821). Famous bearers of the 20th century include author John Steinbeck (1902-1968), assassinated American president John F. Kennedy (1917-1963), and musician John Lennon (1940-1980).
The forms Ian (Scottish), Sean (Irish) and Evan (Welsh) have also been frequently used in the English-speaking world, as has the medieval diminutive Jack.
The name became popular in the English-speaking world outside of Ireland in the middle of the 20th century, and elsewhere in Europe in the latter half of the 20th century. Famous bearers include the American actors Kevin Costner (1955-) and Kevin Bacon (1958-). It was also borne by the character Kevin McCallister in the 1990 comedy movie Home Alone.
A famous bearer of the surname was James Madison (1751-1836), one of the authors of the American constitution who later served as president (and after whom Madison Avenue was named).
In the medieval legend of Tristan and Iseult this was the name of a king of Cornwall. It was also borne by the American author Mark Twain (1835-1910), real name Samuel Clemens, the author of The Adventures of Tom Sawyer and Adventures of Huckleberry Finn. He took his pen name from a call used by riverboat workers on the Mississippi River to indicate a depth of two fathoms. This is also the usual English spelling of the name of the 1st-century BC Roman triumvir Marcus Antonius (Mark Antony).
Olivia has been used in the English-speaking world since the 18th century, though it did not become overly popular until the last half of the 20th century. Its rise in popularity in the 1970s may have been inspired by a character on the television series The Waltons (1972-1982) [2] or the singer Olivia Newton-John (1948-2022). In 1989 it was borne by a young character on The Cosby Show, which likely accelerated its growth. It reached the top rank in England and Wales by 2008 and in the United States by 2019.
A famous bearer was the British-American actress Olivia de Havilland (1916-2020).
