Meaning & origin

Leidy is a modern American name that first appeared in Social Security records in 1974, reflecting a pattern of inventive respellings common in contemporary naming. Its meaning is uncertain; it may draw from the Spanish-influenced pronunciation of Layla or function as a phonetic variant of Lady. The name saw its highest usage in 2006, when it ranked 5,722th nationally, but it has been falling in popularity since 2007. Today, roughly 1 in 76,537 newborns receive the name, showing it remains a rare choice. Leidy has not been concentrated in any single U.S. state, suggesting broad but thin use across the country. As a modern creation, it lacks historical depth but offers a distinctive sound familiar to English and Spanish speakers.

Leidy is a modern coinage that first appeared in U.S. birth records in 1974. It likely arose as a Hispanic-influenced adaptation of names like Layla (meaning "night" in Arabic) or Lydia (a Greek place name), or simply as a respelling of the English word "lady." The name gained modest popularity in the 2000s, peaking in 2006, and has since declined.
