Biography

Mór is the daughter of Muirchertach Ó Tuathail ^[1]

Mór O'Toole, in Irish Mor Ui Thuathail (c.1114- 1191), was a Queen-consort of Leinster as the principal first wife of King Dermot MacMurchada. Under Brehon Law, Irish kings were allowed more than one wife. King Dermot's second wife was Sadhbh Ni Fhaolain. ^[2]

Mór was born in Castledermot, Kildare, Ireland in about 1114, the daughter of Muitchertach O'Toole (Ua 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, and 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 Loch Garman, County Wexford, Mor married, as his first wife, King Diarmait Mac Murchada (anglicised as Dermot MacMurrough) of Leinster, making her Queen-consort of Leinster. In 1152, he abducted Derbforgaill Ni Mhaol Seachlainn, the wife of the King of Breifne, Tiernan O'Rourke (Irish: Tighearnán Ua Ruairc).[1]

Dermot and Mor had at least three children:

Conchobhar MacMurrough (died 1167)

Aoife MacMurrough (1145-1188), married 29 August 1170, Richard de Clare, 2nd Earl of Pembroke, known to 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 Domnall Mór Ua Briain, King of Thomond, by whom she had issue.

In 1167, Mor's son Conchobhar was killed by Ruaidrí Ua Conchobair, High King of Ireland, after having been taken hostage while Diarmait waged war against Ruaidrí 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 predeceased her on 1 May 1171 in Ferns, shortly after the Cambro-Norman invasion of Ireland led by their son-in-law, Strongbow.
