Oliver

From Old French Olivier, which was possibly derived from Latin oliva "olive tree" [1]. Alternatively there could be an underlying Germanic name, such as Old Norse Áleifr (see Olaf) or Frankish Alawar (see Álvaro), with the spelling altered by association with the Latin word. In the Middle Ages the name became well-known in Western Europe because of the French epic La Chanson de Roland, in which Olivier is a friend and advisor to the hero Roland.

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.
