Lonny
Masculine · “noble and ready”
Lonny is overwhelmingly a boys’ name — 6,357 boys against 56 girls since 1880.
Lonny is the tail end of a longer name given a friendly ending, and the longer name is almost certainly Alonzo. American English has always been willing to take the last syllables of a name rather than the first — Beth from Elizabeth, Trina from Katrina — and Lon is that habit applied to a Spanish name that had settled comfortably into English by the nineteenth century.

The story of Lonny
Alfonso is a Visigothic name that became the royal name of medieval Castile and León, worn by kings for five centuries. Spanish trimmed it to Alonso, and English-speaking America, meeting it in the Southwest and through Spanish literature, made Alonzo and then cut it to Lon. Adding -y or -ie to a short name is the oldest trick in English affection — it is how Tom becomes Tommy — and by the twentieth century Lonny and Lonnie were being given outright, with nothing longer behind them on the certificate. The name belongs unmistakably to mid-century America.
Meaningscholars disagree
noble and ready
If the parent name is Alonzo, the line runs back to the Spanish Alonso and Alfonso, and behind that to Germanic elements usually read as noble and ready or eager. If the name was built directly from the sound, as some of its generation were, it carries no meaning. Both accounts fit a name that appears in American records early and steadily.

Line the two peaks up, and Lesley's path sketches the road Lonny is walking now.
