Grace O'Malley

Gráinne O'Malley (Irish: Gráinne Ní Mháille, pronounced [ˈgˠɾˠaːn̠ʲə n̠ʲiː ˈwaːl̠ʲə]; c. 1530 – c. 1603) was the head of the Ó Máille dynasty in the west of Ireland, and the daughter of Eóghan Dubhdara Ó Máille.

Upon her father's death, she took over active leadership of the lordship by land and sea, despite having a brother, Dónal an Phíopa Ó Máille. Marriage to Dónal an Chogaidh (Donal "of the war") Ó Flaithbheartaigh brought her greater wealth and influence, reportedly owning as much as 1,000 head of cattle and horses. In 1593, when her sons Tibbot Bourke and Murchadh Ó Flaithbheartaigh (Murrough O'Flaherty) and her half-brother Dónal an Phíopa ("Donal of the Pipes") were taken captive by the English governor of Connacht, Sir Richard Bingham, O'Malley sailed to England to petition for their release. She formally presented her request to Queen Elizabeth I at her court in Greenwich Palace.
