This name has been used in Britain since the Middle Ages. It has been especially popular in Wales, where it is used in honour of the 5th-century patron saint of Wales (also called Dewi), as well as in Scotland, where it was borne by two kings. Over the last century it has been one of the English-speaking world's most consistently popular names, never leaving the top 30 names for boys in the United States, and reaching the top rank in England and Wales during the 1950s and 60s. In Spain it was the most popular name for boys during the 1970s and 80s.
Famous bearers include empiricist philosopher David Hume (1711-1776), explorer David Livingstone (1813-1873), musician David Bowie (1947-2016), and soccer player David Beckham (1975-). This is also the name of the hero of Charles Dickens' semi-autobiographical novel David Copperfield (1850).
Due to the saint's popularity, the name came into general use in medieval Europe, especially in Spain and France. It was also borne by a 16th-century king of Portugal who died in a crusade against Morocco.
This was the name of kings of England, Serbia, and Poland, as well as ten popes. It was also borne by the first Christian king of Hungary (11th century), who is regarded as the patron saint of that country. More recent bearers include British physicist Stephen Hawking (1942-2018) and the American author Stephen King (1947-).
Its modern use as a feminine name may have been influenced by the British-American author Taylor Caldwell (1900-1985). Since 1990 it has been more popular for girls in the United States. Other England-speaking regions have followed suit, with the exception of England and Wales where it is still slightly more popular for boys. Its popularity peaked in America the mid-1990s for both genders, ranked sixth for girls and 51st for boys. A famous bearer is the American musician Taylor Swift (1989-).
This was a common name in classical Greece, and, due to both the saints who carried it and the favourable meaning, it came into general use in the Christian world, being especially popular among Eastern Christians. It was however rare in Britain before the 19th century. Famous bearers include three tsars of Russia (in the Russian form Fyodor) and American president Theodore Roosevelt (1858-1919).
