What Lennon means
Lennon carries the sense of a sweetheart or beloved, from the Irish leannán. A competing derivation reads the same surname as coming from a word meaning cloak or mantle, and reference sources genuinely split between the two rather than agreeing on one.
Where Lennon comes from
Lennon comes from the Irish Ó Leannáin, meaning descendant of Leannán, a byname whose root is generally taken as leannán — a sweetheart, and in older usage a familiar spirit or muse. The rival reading traces it to lenn, a cloak, giving a nickname sense for someone known by what they wore. Both are defensible and neither is settled. As a first name it is almost entirely modern and almost entirely a tribute: it followed John Lennon into use after 1980, and unlike most surname-names it has been given to girls as readily as to boys from the start.
