Meaning & origin

Lydon is an uncommon given name that first appeared on the U.S. Social Security rolls in 1964. It has never cracked the top 1000, reflecting its rarity. The name reached its peak usage in 2014, but since 2010 its frequency has been falling. Lydon does not appear in any recorded top states, suggesting a very scattered distribution across the country. The name's Irish surname origins give it a distinct character, and it may appeal to parents seeking a name with Celtic heritage that remains off the beaten path.

Lydon is an anglicized form of the Irish surname Ó Loideáin, which means 'descendant of Loideán'. The personal name Loideán likely derives from 'loid', meaning 'grey', combined with a diminutive suffix. The surname first emerged in County Galway, Ireland. As a given name, Lydon has been used sparingly since the mid-20th century, possibly influenced by the surname of the punk rock singer John Lydon.
