During the Middle Ages it was very common, and it became a slang word meaning "man". It was frequently used in fairy tales and nursery rhymes, such as 'Jack and the Beanstalk', 'Little Jack Horner', and 'Jack Sprat'. American writers Jack London (1876-1916) and Jack Kerouac (1922-1969) were two famous bearers of this name. It is also borne by American actor Jack Nicholson (1937-).
RONALDmScottish, English Scottish form of RAGNVALDR, a name introduced to Scotland by Scandinavian settlers and invaders. It became popular outside Scotland during the 20th century. A famous bearer was American actor and president Ronald Reagan (1911-2004).
WENDYfEnglish In the case of the character from J. M. Barrie's play 'Peter Pan' (1904), it was created from the nickname fwendy "friend", given to the author by a young friend. However, the name was used prior to the play (rarely), in which case it could be related to the Welsh name GWENDOLEN and other names beginning with the element gwen meaning "white, fair, blessed". The name only became common after Barrie's play ran.
