The O'Malley clan is a prominent Irish family with roots tracing back to the ancient Gaelic nobility. They are primarily associated with the province of Connacht, particularly in County Mayo. The clan's name, derived from the Gaelic "Ó Maolmhuire," means "descendant of Maolmhuire," indicating a lineage connected to a historical figure. Historically, the O'Malleys were known for their seafaring skills and played a significant role in maritime activities along the West Coast of Ireland. One of the most famous members of the clan is Gráinne Mhaol, also known as "Granny O'Malley," a legendary pirate and chieftain in the 16th century who defied English rule.
