| Dermot MacMurrough |
Sometime about 1140 in Loch Garman, County Wexford, Mór was married to King Diarmait Mac Murchada of Leinster as his second wife, making her Queen-consort of Leinster. One of Dermot and Mor's three children, Eva, 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, Countess of Pembroke, who became the heiress to her father's titles and estates.
Isabel Marshal, nee de Clare, was the mother of Isabel de Clare, nee Marshal, who in turn was the mother of Isabel Bruce, nee de Clare. The last mentioned Isabel was, of course, the grandmother of Robert the Bruce, King of Scotland.
28: Mor MacMurrough (nee O'Toole) was one of two wives of King Dermot, Irish men at that time in history allowed more than one wife, under Brehon Law.
27: Eva (Aoife) de Clare (nee MacMurrough) married the leader of the Norman invasion force on 29 August 1170 at Reginald's Tower, Waterford, at the request of her father. Under early Irish Law, he was not allowed to give his daughter away, and Aoife (or Eva) had the choice of whom she married. She agreed to follow her father's advice.
26: Isabel Marshal (nee de Clare), Countess of Pembroke, was the wife of the famed Lord Marshal of England to four successive kings, William Marshal, 1st Earl of Pembroke.
25: Isabel de Clare (nee Marshal) (9 October 1200 - 17 January 1240), one of ten offspring of William Marshal and Isabel de Clare, married Gilbert de Clare, Earl of Hertford and Earl of Gloucester. Prior to their marriage, Isabel and Gilbert were related via eight steps.
Although Isabel married Gilbert, 20 years her senior, at Tewkesbury Abbey on her seventeenth birthday, the marriage was an extremely happy one, despite the age difference, and the couple had six children. Isabel's husband Gilbert joined in an expedition to Brittany in 1229, but died 25 October 1230 on his way back to Penrose, in that duchy. His body was conveyed home by way of Plymouth and Cranborne, to Tewkesbury, where he was buried at the abbey where they were married.
Isabel was a young widow, only 30 years old. She had proven childbearing ability and the ability to bear healthy sons; as evidenced by her six young children, three of whom were sons. These were most likely the reasons for both the proposal of marriage from Richard, 1st Earl of Cornwall, and Isabel's acceptance of it, despite the fact that her husband had just died five months previously. The two were married on 30 March 1231 at Fawley Church, much to the displeasure of Richard's brother King Henry, who had been arranging a more advantageous match for Richard. Isabel and Richard got along well enough, though Richard had a reputation as a womanizer and is known to have had mistresses during the marriage. They were the parents of four children, three of whom died in the cradle.
Isabel died of liver failure, contracted while in childbirth, on 17 January 1240, at Berkhamsted Castle. She was 39 years old. When Isabel was dying she asked to be buried next to her first husband at Tewkesbury Abbey, but Richard had her interred at Beaulieu Abbey, with her infant son, instead. As a pious gesture, however, he sent her heart, in a silver-gilt casket, to Tewkesbury.
24: Isabel Bruce (nee de Clare) (2 November 1226 - 10 July 1264), one of six offspring of Gilbert and Isabel, married Robert Bruce "the Competitor", fifth Lord of Annandale and the grandfather of Robert Bruce, seventh Lord of Annandale, Earl of Carrick and King of Scotland.
