Meaning & origin
Lilley is a modern spelling variant that has seen modest use in the United States since its first recorded appearance in 1919. The name reached its peak popularity in 2008, but has been on a declining trajectory since then, with a rank of 13,208 in 2025. At that rank, approximately 1 in every 267,878 baby girls received the name. While its exact origins are uncertain, Lilley likely draws from the flower name Lily or from an English surname. Its upward trend in the 2000s aligns with the popularity of similar floral and diminutive names, though it remains far less common than the standard Lily or Lillie. Top states for the name are not available in the data, suggesting it is widely spread rather than regionally concentrated.
Lilley likely emerged as a modern spelling variant of Lily, the flower name from Latin lilium. Its use as a given name may also be influenced by the English surname Lilley, derived from place names meaning 'clearing where flax grows' in Old English. The name has been in sporadic use in the United States since the early 20th century, with a notable rise in popularity in the 2000s.
