  [SUSANNA KEENE.FTW]
  
  Stammtafeln says she is the daughter of Henry, Margrave of Mark
  (d 886).
  
  Current consensus (as summarised by E.Hlawitschka, in
  Rheinische
  Vierteljarhrblatter, 1974, p141ff) is that she was a daughter
  of Margrave Henry who died at paris against the Normans
  28.8.886 (he also often appears with other titles: Duke of the
  Austrasians, is one of them). Her mother was according to the
  same author) was probably a grand-daughter of St.Ida (d.c.820)
  and the Saxon Count Egbert (flor. 809-11).
  
  I can only refer back to the same article: there was a family
  in Saxony
  at this time who historians call the Egbertiner or Cobbonen
  after their
  most distinguished members. The details about Ida and Egbert's
  family
  come from two sources: her Life (written 980/3) and the
  Translatio
  S.Pusinnae (c.860/77). St.Ida was the founder of Herford, a
  convent
  in Saxony. Her Life calls Egbert duke of all saxony between the
  Rhine
  and the weser appointed by Charlemagne. A count Egbert appears
  in
  the Royal frankish annals in 809 and 811 concerned with the
  boundary
  between Saxony and the Denmark. Their children included Warin
  abbot of Corvey 826-56, and Count Cobbo the Elder (d. fl 845),
  and
  Addila abbess of Herford. This family continued to be important
  in
  Saxony in the 10th century.
  
  Ida is said to be the daughter of a Frankish count (though
  Hlawitschka tries to make her a daughter of Carloman I d.771,
  wrongly I think). As Egbert of Wessex became king in 802 (?),
  it would seem unlikely that he could have two different careers
  in two different countries, at the same time. Unless the ASC
  date 802 is wrong.

  PS: the Egbertiner are also mentioned in an article in English
  (about
  the revolt of the Stellinga in Saxony c.840-43), in Speculum
  70, 1995, p488.
  Speculum is an American journal on Medieval History.
  
  Dutch "Winkler Prins" encyclopedia says Henry was via his
  mother a
  grandson of Louis the German (who was a grandson of
  Charlemagne). The

  Waitz (1885,
