Meaning & origin

Jillayne is a rare American coinage that first appeared in Social Security records in 1952, during a period of creative name blending. Its peak year was 1963, but it never approached the popularity of similar names like Lorraine or Darlene. The name's trajectory has been stable and low, with no resurgence in recent decades. It was most common in the 1960s, but did not concentrate in any particular state. Families choosing Jillayne today are reviving a name that was a brief, inventive alternative to more common Jillian or Jilaine forms. Its rarity and distinctive sound appeal to those seeking a name that feels familiar yet unusual.

Jillayne is a modern coinage, emerging mid-20th century in the United States. It likely combines the name Jill (a short form of Jillian, from the Latin Iuliana) with the fashionable -ayne or -aine suffix seen in names like Lorraine or Elaine. The name first appeared in U.S. records in 1952 and saw peak usage in 1963. It was never common, remaining a creative variation of more established names.
