Egbert fled, perhaps to Charlemagne's court having strong Frankish connections thought his Kentish ancestry, possibly arriving around 792.Offa had also angered Charlemagne by trying to marry their children, Charlemagne's daughter and Offa's son, where as Charlemagne broke off all relations with England.

Mike Ashley's "British Kings & Queens"

Cadwallon ap Einion (c.460-534; reigned from c.500), also known as Cadwallon Lawhir ('Long Hand') and Cadwallon I, was a king of Gwynedd.

According to tradition, Cadwallon ruled during, or shortly after, the Battle of Mons Badonicus, and King Arthur's victory over the Saxons (depending on which date you believe, said battle accorded either sometime between the early 490s and the mid 510s). Although it is unlikely that Cadwallon himself was present at the event, he would likely have benefitted from the period of relative peace and prosperity throughout Britain that it procured. The most momentous military achievement of Cadwallon's reign was the final expulsion of Irish settlers on Ynys Mon (Anglesey), and the absorption of that island, which would later become the cultural and political base of the kingdom, into Gwynedd.

Cadwallon's second name, Lawhir, referred to an actual physical characteristic of the man: he apparently had unusually long arms. Iolo Goch claims that he could "reach a stone from the ground to kill a raven, without bending his back, because his arm was as long as his side to the ground."

According to Gildas, Cadwallon's son, Maelgwn, murdered his uncle to ascend to the throne, which suggests that someone other than Maelgwn himself inherited the kingdom upon Cadwallon's death. No clear evidence exists as to who this "lost king" might be (assuming, of course, that Gildas's account is reliable), but some have suggested the name of Owain White Tooth as the unfortunate heir/victim.

Ottar Egilsson

Ottar ruled the Swedes after his father's death. He did not maintain the friendship with King Frode of Denmark who sent messengers demanding the scatt (property/money/animals) promised to him by Ottar's father. Ottar said no, no Swede had ever paid a scatt to a Dane, so the next summer, Frode ravaged Sweden. The following summer Frode invaded northward, Ottar heard  Frode was not at home so he proceeds westward to the Sound, and sails north about to Jutland, lands at Lymfjord and plunders the Vend district. The two earls left in charge, Vatt and Faste, came upon Ottar unexpectedly and fought at Lymfjord. The Danes won, left Ottar's body to the beasts, and sent a wooden crow back to Sweden with word with it that their king, Ottar, was no better than it; and from this he was called Ottar Vendelcrow.
Heimskringla, Ynglinga Saga, Section 31

Ohthere, Ohtere (the name is sometimes mispelt Ohþere), or Ottar Vendelkråka (Vendelcrow) (ca 515 - ca 530) was a king of the Swedish house of Scylfings. Ohthere is considered to be a fairly historical king of Sweden, the memory of whom has been conveyed by Beowulf, Norse sagas and Swedish tradition (see also Origins for Beowulf and Hrólf Kraki). His name has been reconstructed as Proto-Norse *Ohtaharjaz or *Ohtuharjaz [1]. He was the son of Ongenþeow and the brother of Onela. He was the father of Eadgils, and according to Beowulf he also had a son named Eanmund.
