  • ID: I01407
  • Name: Sibyl (Suthen) BIORNSDOTTIR , of Northumbria 1
  • Sex: F
  • ALIA: Sibyl Biornsdottir of /Northumbria/
  • Birth: ABT 1010 in Northumbria, England
  • Death: 1040 2
  • Note:
    Note: Turton's Plantagenet Ancestry has Sibyl as daughter of Sigurd, but I think it more likely she was his sister. The dates just seem entirely incompatible with her being born that late. Based on the e-mail from Betty Knoche, referring to the Mammoth Book on English Kings & Queens, by Mike Ashley, I am going to make her a sister (I have used slightly different dates, making her a younger sister).


    The following e-mail from Betty Knoche, BGKnoche AT, gives a source who states that Sibyl was a sister (not daughter of Sigurd/Syward:

    Hi Jim

    You noted that you thought Sibyl was the sister of Sigurd rather than daughter.

    According to British Kings et al, the comment is "Sybilla, sister (some records say dau.) of Siward, earl of Northumbria:..." I have a note that says Siward Biornsson was born abt 1020 with a sister born abt 1010 and they are the children of Biorn Ulsinsson, Earl in Denmark (born abt 975 in Roskilde, Denmark). I don't know if this helps or hinders!



    The following was given in a post-em by Curt Hofemann, curt_hofemann AT

    Gerald Paget "The Lineage and Ancestry of H.R.H. Prince Charles, Prince of Wales" p56 & 153 indicates that her father was Bjorn Bearsson & her brother was Siward Earl of Northumbria.

    George Andrews Moriarty "The Plantagenet Ancestry of King Edward III and Queen Philippa" p30 indicates that Siward was her cousin.

    Todd A Farmerie in a 23 Feb 2002 msg to SGM stated:
    There is no contemporary or near-contemporary documentation of this (that Sybil FitzSiward was the wife of Duncan I MacCrinan). The best you get is Siward being called a kinsman of Malcolm, Duncan's son (likewise, the name Sybil in this context is not workable). If such a connection is true, I would think that the relationship was through Siward's wife.

    Stewart Baldwin on the Henry Project webpage:
    identifies her as "Suthen" (Sybil certainly doesn’t sound Danish to me. Curt) & states:
    Suthen's name is known only from one of the Scottish king lists ("Regnal List I"), which gives the name of the mother of Malcolm III in an interlined addition [KKES 284]. ESSH 1: 596 cites the late fourteenth century Scottish historian John of Fordun [iv, 44] as stating that Duncan had married a kinswoman of Siward of Northumbria. Given Siward's support of Malcolm, that is plausible enough, but there does not appear to be any justification for attempts to define a more specific relationship between Suthen and Siward.
