This is the Final Profile ID for Suthen, wife of Duncan I of Scotland.

Suthen/Sybil is being consolidated in this profile. Due to her unknown parentage, her LNAB has been determined as UNKNOWN.

Take care when merging.

There is confusion surrounding the origins of Sybill/Suthen. Conflicting theories claim she is either a: cousin, sister, or daughter of Siward, Earl of Northumbria. Therefore, her LNAB is "UNKNOWN".
  • Siward had 2 known children: Waltheof of Bamburg and (unproven) Osbeorne (d.27 Jul 1054).
  • "[SIBYLLA] . The Chronicle of John of Fordun states the mother of Malcolm and Donald Bane, Duncan's sons, was "the cousin of Earl Siward". This info is not in any earlier source and should be considered dubious" (Medieval Lands)

brilliant summary Sheri, in some ways it makes life more difficult as a genealogist, but also simpler - and as Sybilla/Suthen could never have been Bjornsson, I have eliminated it as a aka

Old Norse naming traditions - Has a rule been set for this?

Since there were no separate countries like we have today in Scandanavia, the patrynomic systems which vary from Denmark to Finland could all be standardized in the old Norse way: -son for "son of" and -sdottir for daughter of (father's first name) - Nelsson, Nelsdottir.

This would streamline names. Since 1850 only Iceland still uses the feminine ending. All others are masculine and no longer change with generations. Another possibility is to default to father's first name without a gender ending so siblings can be matched more easily. (Nels and Nels) In any case, all old Norse names should begin with the father's first name, which means the names will change with each generation in ancient times.

I imagine that Sibyl is actually Biornsdotter - rather than son??
