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.
