Surname Series: Leahy/Lahy

This episode of The History and Heritage Podcast examines the Irish surname Leahy, along with variants such as Lahey and Leahey. Although often treated as a single family name, Leahy derives from two distinct Gaelic lineages with different meanings, social roles, and regional histories. The episode explores how anglicisation, regional pronunciation, and administrative record-keeping caused separate families to be recorded under the same spellings. A grounded exploration of language, identity, and the hidden complexity behind a familiar Irish name.
