Meaning & origin

Lonnie reached its peak popularity in 1901, when it ranked highest among U.S. baby names. Since 1985, its use has been steadily falling. The name was most common in the early 1900s and has been especially favored in states like Arkansas, Missouri, and Ohio. Though it has never disappeared, its frequency has dropped significantly, and today it is a rare choice. Lonnie's trajectory shows a long decline from a once-familiar nickname to a name that now feels distinctly old-fashioned.

Lonnie originated as a diminutive of Alonzo (a Spanish variant of the Germanic name Alfonso) and also of Lawrence (from the Roman name Laurentius). It emerged in the United States in the late 19th century and was most popular in the early 1900s, particularly in the South and Midwest.
