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).
