Meaning & origin

Keygan is a modern American invention, first appearing in U.S. birth records in 1996 and reaching its peak popularity in 2008, with a gradually declining trajectory since 2009. The name shares phonetic similarities with Irish surnames like Keegan and Reagan, but its spelling is firmly a contemporary creation. It has never appeared in the top 1000 names for any year, and its one-in-N ratio is effectively negligible. While no single state recorded it with enough frequency to appear in top-state lists, Keygan's usage pattern mirrors that of many invented names rooted in the sound patterns that gained traction in the late 1990s and early 2000s. Parents choosing Keygan today are selecting a rare, modern-sounding name with a slim but documented history.

Keygan is a modern coinage, first recorded in the United States in 1996. It appears to be a creative spelling variation of Keegan, an Irish surname derived from the Gaelic Mac Aodhagáin, meaning 'son of Aodhagán' (a diminutive of Aodh, 'fire'). However, the specific form Keygan has no direct Irish antecedent and is best understood as a contemporary invented name, likely influenced by the fashionable -an ending and phonetic similarity to established names like Keegan and Reagan. Its use has been primarily in the United States, where it peaked in 2008.
