      1. “Royal Ancestry: A Study in Colonial & Medieval Families,” Douglas Richardson (2013):
      “MAUD OF NORTHUMBERLAND, daughter and co-heiress, born about 1072 (aged 18 in 1090). She married (1st) in or before 1090 SIMON DE SENLIS, in right of his wife, Earl of Huntingdon and Northampton, and, lord of Conington, Huntingdonshire, Tottenham, Middlesex, Fotheringay, Northamptonshire, etc. They had two sons, Simon [Earl of Northampton] and [Saint] Waltheof [Prior of Kirkham, Abbot of Melrose], and one daughter, Maud. By an unknown mistress, he had an illegitimate son, Simon. He went on crusade in 1095. In 1098 he was captured during the Vexin campaign of King William Rufus in 1098, and was subsequently ransomed. He witnessed King Henry I's charter of liberties issued at his coronation in 1100. He attested royal charters in England from 1100-3, 1106-7, and 1109-11. Sometime in the period, 1093-1100, he and his wife, Maud, founded the Priory of St. Andrew's, Northampton. He reportedly built the first castle at Northampton. He witnessed a grant of King Henry I to Bath Abbey 8 August 1111 at Bishop's Waltham, as the king was crossing to Normandy. Simon and his wife, Maud, gave the tithe of Tottenham, Middlesex to the monks of St. Andrew's, Northampton. SIMON DE SENLIS, Earl of Huntingdon and Northampton, subsequently went abroad and died at La Charité-sur-Loire, and was buried there in the new priory church. The date of his death is uncertain. His widow, Maud, married (2nd) before Midsummer 1113 DAVID I, King of Scots [see SCOTLAND 2], 6th and youngest son of Malcolm III Canmore, King of Scots, by his 2nd wife, Margaret [see SCOTLAND I for his ancestry]. He was probably born about 1085. They had two sons, Malcolm and Henry [Earl of Northumberland], and two daughters, Clarisse and Hodierne. David was recognized as Earl of Huntingdon to the exclusion of his step-son, Simon; the earldom of Northampton reverted to the crown. As Earl of Huntingdon, he made various grants to St. Andrew's, Northampton. In 1113 he founded an abbey at Selkirk, afterwards removed to Kelso, and gave it land at Hardingstone and Northampton. He founded another abbey at Jedworth in 1118. He succeeded, his brother, Alexander I, as King of Scotland 25 April 1124. In 1127 he joined in the Barons' recognition of Empress Maud to succeed her father on the throne of England. When Stephen seized the crown, David took arms against him. His wife, Queen Maud, died 1130 or 1131, and was buried at Scone. About 1132 he gave the church of Tottenham, Middlesex to the canons of the church of Holy Trinity, London. In 1136 King David I resigned the earldom of Huntingdon to his son, Henry, who did homage to Stephen. David was defeated at the Battle of Standard 22 August 1138. DAVID I, King of Scots, died at Carlisle 24 May 1153, and was buried at Dunfermline, Fife.

This earldom came to King David by right of his wife, Maud daughter of Earl Waltheof, but he was her second husband and his claim was disputed by Simon de Senlis II who was Maud's son by her first marriage. Stephen was predisposed towards Simon (who supported him loyally) but anxious not to make an enemy of King David if he could help it, and he seems to have aimed at a compromise whereby Northampton would be detached from the earldom of Huntingdon and made a separate earldom for Simon. So far as Huntingdon was concerned, he granted it to King David's son Henry at the Treaty of Durham (5 February 1136). Henry presumably forfeited it during the Scottish war of 1138, but held it again from the second Treaty of Durham (9 April 1139) till the end of 1141, when he finally lost it. It was subsequently held by Simon de Senlis II together with Northampton (G.W.S. Barrow, in Regesta Regum Scottorum i. 102)."). Tait Medieval English Borough (1968): 154-155 ([King William Rufus] apparently ... rewarded the loyalty of Henry of Newburgh and Simon of Senlis with the earldoms of Warwick and Northampton and the lordships of those towns. Simon as the son-in-law of Waltheof had a hereditary claim to the earldom, though not to the town ... It has been doubted whether Simon received the earldom before Henry l's time (Farrer, Honors and Knights' Fees, ii. 296), but he attests a charter of the previous reign as earl (Davis, op. cit., no. 315) and was already earl at Henry's coronation. There is some evidence that Henry I granted the earldom of Northampton as well as that of Huntingdon to David of Scotland, the husband of Simon's widow, but he kept the lordship of the town in his own hands and it was being farmed from the Crown in 1130.).

      “DAVID I, King of Scots, youngest son by his father's 2nd marriage, probably born about 1085. He married before Midsummer 1113 MAUD OF NORTHUMBERLAND, widow of Simon de Senlis, Earl of Huntingdon and Northampton (living 8 August 1111) [see BEAUCHAMP 3], and daughter and co-heiress of Waltheof, Earl of Northumberland, by Judith, daughter of Lambert, Count of Lens [see BEAUCHAMP 2 for her ancestry]. She was born about 1072 (aged 18 in 1090). They had two sons, Malcolm and Henry [Earl of Northumberland], and two daughters, Clarice and Hodierne. David was recognized as Earl of Huntingdon to the exclusion of his step-son, Simon; the earldom of Northampton reverted to the crown. As Earl of Huntingdon, he made various grants to St. Andrew's, Northampton. In 1113 he founded an abbey at Selkirk, afterwards removed to Kelso, and gave it land at Hardingstone and Northampton.

      3. “Royal Ancestry: A Study in Colonial & Medieval Families,” Douglas Richardson (2013):
      “JUDITH OF LENS, born about 1054. She married after January 1070 WALTHEOF, Earl of Northumberland, lord of Potton, Bedfordshire, Waltharnstow, Essex, Conington, Leighton Bromswold, Little Catford, and Sawtry, Huntingdonshire, Barnack, East Farndon, Fotheringay, Harringworth, and Lilford, Northamptonshire, etc., son and heir of Siward, Earl of Northumberland, by Ælfflaed, daughter of Earl Ealdred. They had two daughters, Maud [Queen of Scotland] and Alice. He was still young at the death of his father in 1055. He was active against the Norman in the northern counties and especially at York in 1069. In 1070 he made his peace with King William the Conqueror. He occurs as one of the witnesses to King William's charter to Wells dated 1068. He was present at the marriage of Ralph de Wader at Exning, Cambridgeshire, where the guests entered into a conspiracy against the king. In this he was to some slight extent implicated, but acting on the advise of Archbishop Lanfranc, he crossed over to Normandy to the king, and disclosed the matter to him. The conspiracy having been crushed, the king kept Waltheof with him. But he was accused by his wife, Judith, of more than a mere knowledge of the plot. After a year's deliberation, during which he was imprisoned at Winchester, Waltheof was executed at Winchester, Hampshire 31 May 1075 (or 1076). Two weeks afterwards the king allowed his body to be removed to Croyland Abbey, Lincolnshire, where the abbot buried him in the chapterhouse; his remains were subsequently translated into the church near the altar. At an unknown date, Judith was granted the manor of Elstow, Bedfordshire by her uncle, King William the Conqueror. Sometime prior to 1086, she founded a nunnery at Elstow and endowed it with the vill. She was living in 1086, and presumably died about 1090.
