OLeannain

OLeannain is a surname of Irish origin. It is an anglicized form of the Gaelic name Ó Liatháin. The prefix Ó indicates a descendant of, and Liatháin is a personal name thought to mean "little grey one" or "little swift one". The O'Leannain sept was historically associated with the province of Munster, particularly in the area that is now County Cork. Early references suggest they were a notable family in that region. Over centuries, as with many Irish surnames, the spelling has evolved and diversified. While O'Leannain is one form, variations such as O'Lehane, O'Lehane, and Lehane are also common and share the same ancestral roots. The surname is found in Ireland and has also been carried to other parts of the world through emigration, particularly to countries like the United States, Canada, Australia, and the United Kingdom. Individuals bearing the OLeannain surname today likely trace their lineage back to this ancient Irish sept.
