Due to the popularity of the biblical character, the name came into use in England during the Middle Ages. Though it became rare by the 15th century, it was revived after the Protestant Reformation. Famous bearers of this name include English author Daniel Defoe (1660-1731), Swiss mathematician Daniel Bernoulli (1700-1782), and American frontiersman Daniel Boone (1734-1820).
Possibly taken from the plant family, Nerium oleander (flowering shrub known as oleanders), Cascabela thevetia (yellow oleander), Acacia neriifolia (oleander wattle); or a species of moth, Daphnis nerii (oleander hawk-moth).
In the complex language of love practiced during the time of Queen Victoria, the Oleander flower means caution.
A diminutive use of Oleander could be Ollie, Lee, Lee-Ann, or Anders.
Due to the renown of Saint Paul the name became common among early Christians. It was borne by a number of other early saints and six popes. In England it was relatively rare during the Middle Ages, but became more frequent beginning in the 17th century. In the United States it was in the top 20 names for boys from 1900 to 1968, while in the United Kingdom it was very popular from the 1950s to the 80s. It has also been heavily used in Germany and France and continues to be popular there, though it is currently on the decline in the English-speaking world.
A notable bearer was the American Revolutionary War figure Paul Revere (1735-1818), who warned of the advance of the British army. Famous bearers in the art world include the French impressionists Paul Cézanne (1839-1906) and Paul Gauguin (1848-1903), and the Swiss expressionist Paul Klee (1879-1940). It is borne by actor Paul Newman (1925-2008) and the musicians Paul Simon (1941-) and Paul McCartney (1942-). This is also the name of the legendary American lumberjack Paul Bunyan and the fictional Paul Atreides from Frank Herbert's novel Dune (1965).
Before 1980, this was an uncommon masculine name in America. During the 1980s and 90s this name steadily increased in popularity for both boys and girls, and from 2003 onwards it has been more common for girls in the United States. Elsewhere in the English-speaking world, such as the United Kingdom and Australia, it has remained largely masculine.
This name was later borne by three other English kings, as well as rulers of Scotland, Sicily (of Norman origin), the Netherlands and Prussia. Other famous bearers include William Wallace, a 13th-century Scottish hero, and William Tell, a legendary 14th-century Swiss hero (called Wilhelm in German, Guillaume in French and Guglielmo in Italian). In the literary world it was borne by dramatist William Shakespeare (1564-1616), poet William Blake (1757-1827), poet William Wordsworth (1770-1850), dramatist William Butler Yeats (1865-1939), author William Faulkner (1897-1962), and author William S. Burroughs (1914-1997).
In the American rankings (since 1880) this name has never been out of the top 20, making it one of the most consistently popular names (although it has never reached the top rank). In modern times its short form, Liam, has periodically been more popular than William itself, in the United Kingdom in the 1990s and the United States in the 2010s.
