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).
The English names Jacob and James derive from the same source, with James coming from Latin Iacomus, a later variant of the Latin New Testament form Iacobus. Unlike English, many languages do not have separate spellings for the two names.
In England, Jacob was mainly regarded as a Jewish name during the Middle Ages [1], though the variant James was used among Christians. Jacob came into general use as a Christian name after the Protestant Reformation. In America, although already moderately common, it steadily grew in popularity from the early 1970s to the end of the 1990s, becoming the top ranked name from 1999 to 2012.
A famous bearer was Jacob Grimm (1785-1863), the German linguist and writer who was, with his brother Wilhelm, the author of Grimm's Fairy Tales.
This name is borne by a Jewish woman in Walter Scott's novel Ivanhoe (1819), as well as the title character (who is deceased and unseen) in Daphne du Maurier's novel Rebecca (1938).
