♀Agnes de Sully

Agnes de Sully was a French noblewoman of the twelfth century and the mother of Margaret de Sully, Countess of Eu. She was the twenty-sixth great-grandmother of Nancy Jane Blanchard (1929–2006), through her daughter Margaret de Sully (died about 1145).

She is said to have been the younger daughter and sole heir of Gilon de Sully, Sire de Sully-sur-Loire, and the wife of Guillaume de Champagne, Sire de Sully, a brother of King Stephen of England. Their daughter Margaret married Henry, Count of Eu, as his third wife, and was the mother of John of Eu.

Notes

Sources

Agnes’s parentage, her marriage to Guillaume and their daughter Margaret are given in the Complete Peerage (2nd edition, vol. 5, 1926, under Eu, p. 156), in the account of Henry, Count of Eu: Henry “m., 3rdly, Margaret, da. of Guillaume de Champagne, Sire de Sully (br. of King Stephen, and 1st s. of Etienne, Count of Champagne, Brie, Blois, and Chartres) by Agnes, yr. da. and sole h. of Gilon de Sully, Sire de Sully-sur-Loire”. Her mother’s name is not known, and the peerage gives no dates or places for Agnes’s own life.

Margaret’s descent

The line from Margaret to Nancy Jane Blanchard runs through her son John of Eu; see the page for Margaret de Sully.
