    Sibyl (or Adela or Lucia) Corbet, living 1157, daughter and coheir of Robert Corbet, mistress of Henry I, lady of Alcester, co. Warwick and of Pontesbury and Woodcote, co. Salop (by Henry I she was mother of Reginald Fitz Roy, Earl of Cornwall). [Ancestral Roots]


    The following additional info was supplied by Curt Hofemann, curt_hofemann AT

    no evidence to prove that Henry I married Sibyl [Ref: Sheppard Apr65 p96]

    It is because of Henry I's personal propensities that we know something of two Corbet women who occur in the records of this period. Of his numerous mistresses Sibyl Corbet, elder daughter of Robert fitz Corbet of Longden, must have been a favourite since she bore four, possibly five, of Henry's illegitimate children. [Ref: CP XI Appendix D]

    She had a younger sister Alice. Where, when and how the liaison began between Henry and Sibyl is a mystery. He had already had children by various mistresses: among the oldest must have been Juliane, who married Eustace de Pacy lord of Breteuil in 1103, and rebelled against her father; and Robert, born of an unknown woman of Caen, who was created earl of Gloucester by his father in 1122. [Ref Corbet citing: CP V:683: the suggestion that he was the son of Sibyl Corbet is probably correct]

    The known children by Sibyl Corbet were Rainaud de Dunstanville, his brother William and sisters Gundred and Rohese; it is also possible, but not certain, that Sibyl was the mother of the king's illegitimate daughter Sibyl who was married to Alexander after he became king of the Scots in 1107. [Ref: Corbet citing: A.C. Lawrie, Early Scottish Charters, Glasgow 1905:charter XXXVI to Scone Priory, Alexander I, c. 1120, witnessed by Queen Sibyl and her brother William; she died 12 June 1122 on an island in Loch Tay to which Alexander granted charter XLVII, to canons of Scone]

    Note 2: Corbet = The Corbett Study Group,
    specifically: The Anglo Norman Corbets by Barbara Coulton.



    The following material was excerpted from The Corbet Study Group, J.C. Nobel, online at

    The Anglo Norman Corbets by Barbara Coulton

    Prominent at Matilda's 'court' were several connections of the Corbet family through Sibyl and her sister Alice. Sibyl had married Herbert fitz Herbert, a son of the chamberlain of Henry I; Alice married a kinsman of Brien fitz Count, of Wallingford, one of the empress's main supporters: he was William Boterel of Botreaux. Sibyl's son Herbert fitzHerbert married Lucy, daughter of Miles earl of Hereford. . . .

    We do not know when or where Sibyl and her sister Alice died, but there is an odd footnote to their history in an old account of Asthall church in Oxfordshire. "On the north side of the church ... is the effigy of a female figure recumbent, on a stone coffin, situated within an elegantly Gothic arch. It is said to contain the remains of Alice Corbett, concubine to King Henry I., the daughter of Sir Robert Corbett of Warwickshire." So a memory lingered, though confused.

    Note: Was this "confused" effigy of Sibyl rather than Alice? Or was Alice also a mistress of Henry I?
