Names From Shakespeare's Plays

A compilation of names William Shakespeare used in his work that could be names for modern day babies!

Jourdain

Mercutio

Similar in sound to the French "Thibault", which is far more popular, Tybalt is best known as the bloodlustful and brawling cousin of Juliet in Shakespeare's Romeo and Juliet. Perhaps this connotation has kept parents from using Tybalt. However, given the recent fad for all things Theo, Tybalt might offer a familiar yet unusual option for parents who like the meaning but want to swim against the current. Cute nicknames Ty and Tibby might also appeal.

Tybalt

Energetic Willoughby is a familiar last name, but, as yet, makes for a unique choice in the first spot. An unexpected way to get to popular short forms Will and Billy, Willoughby could make an interesting alternative to William.
 
Despite its similarities to the popular classic, Willoughby has a different meaning and origin to the Germanic William. Derived from Old English and Old Norse, it means "farm near the willows" or perhaps "willow town" if you interpret the second element of the name as meaning "settlement". Outdoorsy and nature-connected, Willoughby may appeal to those who like Barnaby and Zebedee. 
 Willoughby Patterne is the protagonist of the George Meredith novel, The Egotist, while Willoughby Sharp was a contemporary artist, curator, critic and founder of the seminal art magazine, Avalanche. There is a classic 1962 British children's novel titled The Wolves of Willoughby Chase by Joan Aiken that was made into a film in 1989.
 
The name was also selected by British reality TV star, Lucy Watson, for her son born in 2023.
