Meaning & origin
Lennan first appeared on the U.S. baby name charts in 2013, a relatively recent arrival. Its peak popularity came in 2016, when it reached its highest rank. Since then, its usage has been falling, reflecting a common pattern for trendy, style-driven names. The name is often considered a feminized or respelled version of the more established Lennon, which itself gained celebrity cachet through John Lennon. With only a handful of bearers each year, Lennan remains a distinctive choice, favored by parents seeking a name that feels modern and unisex. Despite its rarity, its trajectory suggests it is a passing trend rather than a lasting classic.
Lennan is a modern coinage, likely a respelling or variant of the surname Lennon, which itself is an Anglicized form of the Irish surname Ó Leannáin, meaning 'descendant of Leannán' (a byname meaning 'lover, sweetheart'). The name emerged in the 2010s for girls, possibly influenced by the popularity of similar-sounding names like Lennon and Lennox.
