This name has been common (in various spellings) throughout the Christian world, and it became very popular in the Middle Ages. Saint Andrew is regarded as the patron of Scotland, Russia, Greece and Romania. The name has been borne by three kings of Hungary, American president Andrew Jackson (1767-1845), and, more recently, English composer Andrew Lloyd Webber (1948-).
Famous bearers include the uncrowned English queen Lady Jane Grey (1536-1554), who ruled for only nine days, British novelist Jane Austen (1775-1817), who wrote Sense and Sensibility and Pride and Prejudice, British primatologist Jane Goodall (1934-), and American actress Jane Fonda (1937-). This is also the name of the central character in Charlotte Brontë's novel Jane Eyre (1847), which tells of Jane's sad childhood and her relationship with Edward Rochester.
In England Oliver was a common medieval name, however it became rare after the 17th century because of the military commander Oliver Cromwell, who ruled the country following the civil war. The name was revived in the 19th century, perhaps due in part to the title character in Charles Dickens' novel Oliver Twist (1838), about a poor orphan living on the streets of London. It became very popular at the beginning of the 21st century, reaching the top rank for boys in England and Wales in 2009 and entering the top ten in the United States in 2017.
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.
