Ada de Warenne, Queen Mother of Scotland

Coin of Prince Henry of Scotland

Ada de Warenne was born around 1120, daughter of William de Warenne 2nd Earl of Surrey and Isabel de Vermandois. Through her mother, she was a great-granddaughter of Henry I of France and half-sister to twins Waleran and Robert de Beaumont, Count of Meulan and 2nd Earl of Leicester, respectively, and Hugh de Beaumont, 1st Earl of Bedford. Her niece, Isabel de Warenne, would marry William of Blois, the younger son of King Stephen and, following his death, Hamelin, half-brother of Henry II of England. Ada’s family connections were of the highest quality in the Anglo-Norman world.

As a consequence, Ada’s future marriage became an international concern. On 9 April 1139, a peace treaty was concluded between King Stephen of England and King David I of Scots. Primarily negotiated by Stephen’s wife, Queen Matilda – King David’s own niece – the terms were extremely favourable to the defeated Scots. All the lands that Prince Henry of Scotland, King David’s son and heir, had held in 1138 were returned to him, save for the castles at Bamburgh and Newcastle, for which he was recompensed with two towns of equal value in the south. Furthermore, Henry was confirmed as earl of Huntingdon and created earl of Northumbria, a title which encompassed Northumberland, Durham, Cumberland, Westmoreland and the parts of Lancashire north of the Ribble.

Malcolm IV, King of Scots

It was agreed that English law would remain in force in these regions, but that the barons within the earldom were permitted to do homage to Prince Henry, saving only their allegiance to King Stephen. In return, King David and his son promised a permanent peace and provided four hostages. Although the text of the treaty is now lost, it seems likely that the prince’s marriage to Ada de Warenne, sister of the third Earl Warenne and half-sister of the Beaumont twins, was included in the terms of the Treaty of Durham.

Shortly after the treaty was signed, Prince Henry joined King Stephen’s court for a time, accompanying Stephen on campaign, which came with not without a little risk. It was probably during his stay with Stephen’s court that Henry married his bride. Orderic Vitalis claims that the marriage was a love match; however, the timing clearly suggests that the union was a consequence of the 1139 treaty of Durham, perhaps with the intention of drawing Henry into Stephen’s corner by allying him in marriage to his staunchest supporters, the Beaumont twins. On her marriage, which took place sometime between the conclusion of the treaty of Durham and Henry’s return to Scotland, Ada became Countess of Huntingdon and Northumbria and Lady of Haddington and Crail.

Henry was the only surviving son of King David I of Scotland and his queen, Matilda (or Maud), widow of Simon (I) de Senlis, who had died in 1113. Henry’s mother, Matilda, was the daughter of Waltheof, Earl of Northumbria, and Judith, a niece of William the Conqueror. Henry’s older brother, Malcolm, was tragically killed when a toddler; he was reportedly murdered by a Scandinavian monk in his father’s service, who is said to have savagely attacked the child with his artificial iron hand. Needless to say, the murderous monk was executed: David ordered that he be torn apart by wild horses.

On her marriage, Ada became Countess of Huntingdon and Countess of Northumbria. The marriage produced 3 sons and 3 daughters.

William the Lion, King of Scots

Ada never became Queen of Scots as Henry of Scotland died in 1152, a year before the death of David I. On his son’s death, David recognised his grandson and Ada’s eldest son, Malcolm, as his heir. During her son’s reign, Ada became known as The Queen Mother of Scotland. At this time, in her charters, she is most frequently styled ‘Ada comitissa regis Scottorum.’

Born in 1142, Malcolm succeeded to the crown at the age of 11 as Malcolm IV. Also known as Malcolm the Maiden, he died, unmarried, at Jedburgh in December 1165. Ada had been trying to arrange a suitable bride for him when he died.

He was succeeded by Ada’s 2nd son, William I the Lion. William was one of the longest reigning king of Scots in history, ruling for 49 years. He married Ermengarde de Beaumont, a granddaughter of Henry I of England by his illegitimate daughter, Constance. William and Ermengarde had 3 daughters and a son, who succeeded his father as Alexander II in 1214. Their 2 eldest daughters, Margaret and Isabella, are mentioned in Magna Carta. They became hostages of King John following the treaty of Norham in 1209; the English king had promised to marry at least one of them to his son, the future King Henry III, and to find a suitable husband for the other. Both girls married English nobles – eventually. Their brother, Alexander II, married Henry III’s sister, Joan, but the marriage was childless.

Ada and Henry’s 3rd son, David, Earl of Huntingdon, married Matilda of Chester and it is through the daughters of David that Robert the Bruce and John Balliol both based their claims as Competitors to the Scots crown in the 1290s.

Of the 3 daughters, Matilda died young, in 1152. Ada of Huntingdon married Floris III, Count of Holland, in 1161. She had 4 sons and 4 daughters before the count died at Antioch while on the 3rd Crusade, in 1190. Ada’s great-great-grandson, Floris V, Count of Holland, was one of the 13 Competitors for the Scots crown in 1291. Margaret married Conan IV, Duke of Brittany and Earl of Richmond in 1160. She was the mother of Constance, Duchess of Brittany, wife of Henry II’s son Geoffrey and mother of the tragic Arthur of Brittany who was murdered by King John, and Eleanor, the Pearl of Brittany who spent all her adult life in ‘honourable imprisonment’ in England.

St Martin’s Kirk, Haddington

Following her husband’s death Ada played little part in the politics of Scotland. She did, however, take great interest in the futures of her children, arranging the marriages of her daughters and seeking a bride for her son, King Malcolm IV. She later retired to her dower lands at Haddington in East Lothian, given to her by David I and possibly the 1st Royal Burgh in Scotland.

A generous patroness of the Church, Ada de Warenne died in 1178, shortly after founding the nunnery at Haddington She is believed to be buried in the Haddington area, although the exact location of her grave is lost to history. In 1198 her grandson, the future Alexander II, would be born in her old palace at Haddington, after her dower-lands were passed on to her daughter-in-law, Queen Ermengarde.

In a time when men fought and women stayed home, Nicholaa de la Haye held Lincoln Castle against all-comers. Not once, but three times, earning herself the ironic praise that she acted ‘manfully’. Nicholaa gained prominence in the First Baron’s War, the civil war that followed the sealing of Magna Carta in 1215.

A truly remarkable lady, Nicholaa was the first woman to be appointed sheriff in her own right. Her strength and tenacity saved England at one of the lowest points in its history. Nicholaa de la Haye is one woman in English history whose story needs to be told…
