A better fit for the wife of Theoderich may be Regenlind, [sister of Bovo Bishop of Chalons, daughter of ---].
Adam of Bremen names "Sigafrid et Anuleo, nepotes Godafridi" when recording that they fought to succeed after the death of King Hemming as the son of King Harald, but the primary source on which this is based has not yet been identified.
However, Einhard's Annales record that "Anulo nepos Herioldi quondam regis" was one of the claimants to the throne in 812Described as brother of Kings Harald and Reginfred, Hemming must have been captured by Emperor Charlemagne as Einhard's Annales record that "Harioldus et Reginfredus reges Danorum" sent envoys to Emperor Charlemagne in 812 asking for the release of "fratrum suum Hemmingum"The Annales Fuldenses record that "Nordmanni" exacted tribute in "Walchram insulam", where "Eggihardum eiusdem loci comitem et Hemmingum Halbdani filium" were killed "837 XV Kal Iul" and "Dorestadum" was devastated [Ali] (-killed in battle Haithabu 812).
Haralds son King Svend I started raiding England soon after his accession in , culminating in a full-scale invasion in 1013 when Svend succeeded in imposing himself as de facto ruler of the country.
Svends son King Knud I defeated and killed the English king Edmund Ironsides and established himself as king of England in 1016.
It has therefore largely been ignored in the reconstruction of the later generations of the family.
Considerable doubt persists about the precise relationships between the 9th century Danish rulers.Einhard's Annales record that "Harioldus et Reginfredus reges Danorum" who, in the previous year had been expelled from Denmark by "filiis Godofredi", attacked again in 814 but "Reginfridus et unus de filiis Godofredi qui maior natu erat" were killed while "Herioldus" sought protection from the emperor.Einhard's Annales record that the Saxons and Abotrites, with "Baldrico" imperial legate, crossed "Aegidoram fluvium in terram Nordmannorum vocabulo Sinlendi" in 815 to help the deposed Harald King of Denmark, when he was given the territory of Rstringen on the mouth of the Weser in upper Frisia, the first portion of Frankish land to be ceded to the Danes. The early 9th century Danish kings led the Viking expeditions which raided north-west Germany.This brought them into conflict with the Carolingian rulers who were extending their territorial control northwards, which accounts for the interest shown in their activities by contemporary Frankish sources.sets out the outline genealogy of a family referred to as "the Kings of Haithabu".
