According to Genesis in the Old Testament Adam was created from the earth by God (there is a word play on Hebrew אֲדָמָה (ʾaḏama) meaning "earth"). He and Eve were supposedly the first humans, living happily in the Garden of Eden until they ate the forbidden fruit from the tree of knowledge of good and evil. As a result they were expelled from Eden to the lands to the east, where they gave birth to the second generation, including Cain, Abel and Seth.
As an English Christian name, Adam has been common since the Middle Ages, and it received a boost after the Protestant Reformation. A famous bearer was Scottish economist Adam Smith (1723-1790).
As an English name it can also derive from the month of August, which was named for the Roman emperor Augustus.
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).
This name has been used occasionally in England since the 12th century. It was not common in the English-speaking world until the end of the 20th century.
As an English name, Jonathan did not become common until after the Protestant Reformation. A famous bearer was the Anglo-Irish satirist Jonathan Swift (1667-1745), who wrote Gulliver's Travels and other works.
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.
