As an English Christian name, Abraham became common after the Protestant Reformation. A famous bearer was the American president Abraham Lincoln (1809-1865), who pushed to abolish slavery and led the country through the Civil War.
As an English given name, Christopher has been in general use since the 15th century. It became very popular in the second half of the 20th century, reaching the top of the charts for England and Wales in the 1980s, and nearing it in the United States.
In Denmark this name was borne by three kings (their names are usually spelled Christoffer), including the 15th-century Christopher of Bavaria who also ruled Norway and Sweden. Other famous bearers include Italian explorer Christopher Columbus (1451-1506), English playwright Christopher Marlowe (1564-1593), English architect Christopher Wren (1632-1723) and the fictional character Christopher Robin from A. A. Milne's Winnie-the-Pooh books.
Because Elijah was a popular figure in medieval tales, and because his name was borne by a few early saints (who are usually known by the Latin form Elias), the name came into general use during the Middle Ages. In medieval England it was usually spelled Elis. It died out there by the 16th century, but it was revived by the Puritans in the form Elijah after the Protestant Reformation. The name became popular during the 1990s and 2000s, especially in America where it broke into the top ten in 2016.
Hector has occasionally been used as a given name since the Middle Ages, probably because of the noble character of the classical hero. It has been historically common in Scotland, where it was used as an Anglicized form of Eachann.
Known bearers of this name include the Georgian actresses Ia Parulava (b. 1967) and Iamze "Ia" Sukhitashvili (b. 1980).
The name was common among Jews in the Middle Ages, but it was not generally used as a Christian name in the English-speaking world until after the Protestant Reformation. It was moderately popular in the first half of the 20th century, but starting in the 1960s it steadily rose, reaching highs in the 1980s and 90s. The character Rachel Green on the American sitcom Friends (1994-2004) may have only helped delay its downswing.
Notable bearers include American conservationist Rachel Carson (1907-1964), British actress Rachel Weisz (1970-), and Canadian actress Rachel McAdams (1978-).
