Meaning & origin

Lonn is a distinctive spelling variant of the name Lon, which historically appears as a short form of Alonzo. Its use in the United States began modestly in the 1940s, with the first recorded occurrence in 1940. The name reached its peak popularity in 1968, though it never entered the top 1000 names. Since the 1960s, its usage level has remained stable but low, reflecting its status as a rare and unconventional choice. The double-n spelling differentiates Lonn from the more common Lon, adding a slight modern twist. While no specific states show a strong concentration of the name, its history aligns with mid-20th-century naming trends that favored concise, one-syllable names.

Lonn is a modern spelling variant of Lon, which itself is typically a nickname or short form of the name Alonzo. Alonzo is the Italian and Spanish form of the Germanic name Alphons, derived from the elements 'adal' (noble) and 'funs' (ready, prompt), giving the overall meaning 'noble and ready for battle' or simply 'ready for battle'. The spelling with a double n appears to be a 20th-century American innovation.
