History & Origin

Neil is the anglicized form of Irish Gaelic Niall, whose etymology is debated among scholars. The most widely accepted interpretation is 'champion' from Old Irish niadh (warrior). An alternative reading connects it to the Old Irish word for 'cloud'. Niall of the Nine Hostages, the legendary High King of Ireland (c. 379–405 AD), was the progenitor of the powerful Ui Neill dynasty and one of the most significant figures in early Irish history.

Neil entered English use through Scottish and Irish immigration and has been used in the English-speaking world since at least the medieval period. It was popular in the United States particularly from the 1940s through the 1970s. Astronaut Neil Armstrong, musician Neil Young, and scientist Neil deGrasse Tyson represent the name's association with intellectual and creative achievement.

Did you know? Neil Armstrong (1930–2012), who spoke the first words from the surface of the Moon on July 20, 1969, made Neil one of the most historically resonant names in human history — a name associated with the single greatest journey ever undertaken.
