Meaning & origin
Shelagh is an Irish variant of Sheila, itself an anglicization of the Gaelic name Síle. It entered U.S. records in 1942 and saw its peak usage in 1950, a pattern common among Irish names during the mid-20th century. The name has since declined in use and does not appear in the current top 1000. Shelagh's trajectory has been stable at very low numbers in recent decades, reflecting its status as a vintage or niche choice. Its top states of use are generally not concentrated in any particular region, suggesting it has been used sporadically across the country rather than in specific ethnic enclaves. Despite its rarity, Shelagh retains a distinctively Irish character and may appeal to families seeking a name with Gaelic roots and a classic mid-century feel.
Shelagh is an Irish variant of Sheila, itself an anglicization of the Irish name Síle, which is a Gaelic form of Cecilia. The name Cecilia derives from the Latin 'caecus' meaning 'blind'.
