Their followers eventually settled in Friesland, where Godefrid was appointed duke in 882.
During the first half of the 9th century, Denmark appears to have been a unified kingdom under a single ruler, but this unity quickly fell apart.
However, during the second half of the 9th century the picture becomes much less clear.
As will be seen in Chapter 1 of this document, little is known about some of the late 9th century kings beyond their names.
Regino records the marriage in 882 of "Gisla filia Hlotharii" and "rex Godofridus Nordmannorum", she was the daughter of Duke Godefrid & his wife Gisela [Carolingian], which is presumably a guess based on this description in the Vita Mathildis. Regino records the marriage in 882 of "Gisla filia Hlotharii" and "rex Godofridus Nordmannorum".
If this couple's daughter was the mother of Queen Mathilde, the latter's estimated birth date (see below) would need to be pushed forward by several years, which makes the chronology for her known descendants tight.
Einhard's Annales record that news of the death of "Hemmingus Danorum rex" arrived in 812, that "Sigifridus nepos Godofredi regis et Anulo nepos Herioldi quondam regis" both claimed the succession, and that the faction supporting "Anulonis" was victorious, with "fratres eius Herioldum et Reginfredum" being installed as kings The Annales Fuldenses record the death in 812 of "Hemmingo Danorum rege", the succession dispute between "Sigifredo nepos Godofredi regis et Anulo nepos Herioldi", the battle in which both were killed but which Anulo's supporters won, and the accession by "Herioldum et Reginfredum fratres eius regis"Assuming that "nepos" should here be translated as nephew, from the context of these passages it is likely that Sigfrid's parent was a different sibling of King Godofrid from the latter's brother who was King Hemming's father.
His descendants ruled the country until 1412 (Chapter 3).
