Meaning & origin
Lonny emerged as a given name in the United States around 1920, first appearing on the Social Security records in that year. The name peaked in popularity during 1968, when it reached its highest rank among American baby names. Since then, its usage has declined steadily, and in 2025 it ranked 12,008 with an estimated 1 in 341,615 boys receiving the name. The name's trajectory has been stable over the past decade, with no significant revival or decline. While it never cracked the top 1,000 nationally and is not strongly associated with any particular state, Lonny remains a recognizable diminutive alongside similar names like Ronny and Johnny. Its stable but low popularity suggests a name that persists in use without ever becoming widespread.
Lonny is an English diminutive of the name Alonzo, which is the Italian and Spanish form of the Germanic name Alphonsus, derived from the elements 'adal' meaning 'noble' and 'funs' meaning 'ready'. Alternatively, Lonny can be a shortened form of Lancelot, a name of uncertain origin but famously borne by the Arthurian knight.
