About Mór ingen Muirchertaig Uí Thuathail, Queen-Consort of Leinster

Mor was born in Castledermot, Kildare, Ireland in about 1114, the daughter of Muitchertach O'Toole (O'Tuathail), King of the Ui Muirdeaigh, and Cacht Inion Loigsig O'Morda. Her paternal grandparents were Gilla Comgaill O'Toole and Sadb Mael Morda O'Domnail. Her maternal grandparents were Loigsig O'Morda, King of Loigsig and Gormlaith Inion Finn O'Caellaide (O'Kelly).

One of Mor's four half-brothers was St. Laurence O'Toole, Archbishop of Dublin who was canonised in 1225 by Pope Honorius III.

Sometime about 1140 in Lough Carmen, County Wexford, Mor married as his first wife, King Dermot MacMurrough of Leinster, making her Queen-consort of Leinster. His second wife was Sadhbh Ni Fhaolain. In 1152, he abducted the wife of Tiernan O'Rourke, King of Breifny. She was Derbhforghaill Ni Mhaol Seachlainn, who is often referred to as King Dermot's third wife, however, she was in point of fact, his mistress, by whom he had several children.

Together Dermot and Mor had about three children:

   * Conchobhar MacMurrough (died 1167)
   * Aoife of Leinster (1145- 1188), married Richard de Clare, 2nd Earl of Pembroke, known in history as Strongbow, by whom she had two children, including Isabel de Clare, 4th Countess of Pembroke, who became the heiress to her father's titles and estates.
   * Orlachan of Leinster, married Donough More, King of Thomond, by whom she had issue.

In 1167, Mor's son Conchobhar was killed by Rory O'Connor, High King of Ireland, after having been taken hostage while Dermot waged war against Rory with the aim of overthrowing him in order to take his place as the High King.

Queen Mor died in 1191, three years after her eldest daughter, Aoife. Her husband King Dermot had died on 1 May 1171 in Ferns, shortly after the Cambro-Norman invasion of Ireland led by their son-in-law, Strongbow, and which Dermot had himself instigated and abetted.


In Celtic, Mór Uí Thuathail.
