In the New Testament Simon is the name of several characters, including the man who carried the cross for Jesus. Most importantly however it was borne by the leading apostle Simon, also known as Peter (a name given to him by Jesus).
Because of the apostle, this name has been common in the Christian world. In England it was popular during the Middle Ages, though it became more rare after the Protestant Reformation.
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.
This name has been used in England since the 13th century, though it became more common in Scotland where it was borne by several kings. In the 17th century the Scottish king James VI inherited the English throne, becoming the first ruler of all Britain, and the name grew much more popular. In American name statistics (recorded since 1880) this name has never been out of the top 20, making it arguably the era's most consistently popular name. It was the top ranked name for boys in the United States from 1940 to 1952.
Famous bearers include the English explorer James Cook (1728-1779), the Scottish inventor James Watt (1736-1819), and the Irish novelist and poet James Joyce (1882-1941). This name has also been borne by six American presidents. A notable fictional bearer is the British spy James Bond, created by author Ian Fleming in 1953.
This name is borne by the hero in Ali Baba and the Forty Thieves, the tale of a man who finds the treasure trove of a band of thieves. Another famous bearer was the boxer Muhammad Ali (1942-2016), who changed his name from Cassius Clay upon his conversion to Islam.
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, Aaron has been in use since the Protestant Reformation. This name was borne by the American politician Aaron Burr (1756-1836), notable for killing Alexander Hamilton in a duel.
