Rory O'More

Rory Caoch O'More (; 1547) was an Irish noble. He ruled as Lord of Laois until his death in 1547 at the hand of his brother Giolla Pádraig O'More.

Early life Born about 1515, O'More was the son of Connell O'More (d. 1537) and Gormflaith O'Carroll. His brothers were Lysaght, Kedagh, Giolla Pádraig

According to historian William Arthur Jobson Archbold, O'More "early acquired the character of a violent and successful chieftain." O'More's first wife was the daughter of Tadhg O'Dunne.

Power struggle Upon Connell's death in 1537, a dispute broke out between Rory, Lysaght, Kedagh, and their uncle Peter, who was the Tanist in line to head the family. Peter seized the title with the support of Piers Butler, 1st Earl of Ossory. The three brothers refused to accept Peter's lordship, and led by Lysaght (the eldest brother and Lord of Slemargy), they declared war in late 1537.''

O'More responded to Giolla Pádraig's hostility by allying with James Butler, 9th Earl of Ormond; he married Margaret Butler, the Earl's niece, between 1543 and 1544. The prominent Moore family of Carolina in the United States supposedly claimed patrilineal descent from Rory Caoch O'More through his grandson of the same name, though in actuality they were descended from an English family in Devonshire.
