Meaning & origin
Lenn is a rare masculine name that first appeared in U.S. records in 1913, a time when short, punchy names were fashionable. Its peak year was 1918, reflecting a brief uptick during the World War I era, but it has since remained extremely uncommon, with no rank in the top 1000 from that year through 2025. The trajectory of the name is stable at very low usage, never reaching a notable one-in-N rate. Lenn is most plausibly a variant of Len, itself a diminutive of Leonard, the Old High German compound meaning "brave lion." Without widespread adoption, Lenn largely exists as a curiosity for parents seeking a succinct, straightforward name with historical precedent.
