Eligh is an uncommon yet distinctive given name of Irish origin. It is derived from the Irish surname O'Leach, which itself comes from the Irish Gaelic 'O Laoiseach', meaning 'descendant of Laoiseach'. The name Laoiseach is thought to have been a personal name of considerable antiquity, but its exact origins are unclear. Eligh is not typically associated with any specific saint or religious figure, and it does not appear in any historical records as a given name. Therefore, it remains quite rare and unique.
"Eligh has seen fluctuating popularity over time, with a significant spike in the late 19th to early 20th century and another surge starting around the year 2000."
