Matching family tree profiles for Finn
In the 9th century Historia Brittonum Godwulf is mentioned as an ancestor of Horsa and Hengest:
In the meantime, three vessels, exiled from Germany, arrived in Britain. They were commanded by Horsa and Hengist, brothers, and sons of Wihtgils. Wihtgils was the son of Witta; Witta of Wecta; Wecta of Woden; Woden of Frithowald; Frithowald of Frithuwulf; Frithuwulf of Finn; Finn of Godwulf; Godwulf of Geat, who, as they say, was the son of a god, There is some question regarding the ancestor of Godwulf, listed as "Geat" in Historia Brittonum. Regarding these questions, English scholar Hector Munro Chadwick comments:
"The genealogies do not end with Woden but go back to a point five generations earlier, the full list of names in the earlier genealogies being Frealaf—Frithuwulf—Finn—Godwulf—Geat. Of the first four of these persons nothing is known. Asser says that Geat was worshipped as a god by the heathen, but this statement is possibly due to a passage in Sedulius' Carmen Paschale which he has misunderstood and incorporated in his text. It has been thought by many modern writers that the name is identical with Gapt which stands at the head of the Gothic genealogy in Jordanes, cap. 14; but the identification is attended with a good deal of difficulty."
In the Icelandic Prose Edda, a 13th century work by Snorri Sturluson, chapter 3 of the Prologue contains his Euhmerized account of Norse mythology. In this section, Snorri gives a genealogy stating that Guðúlfr is one of the descendants of Thor and Sif. The genealogy also states that Guðúlfr is an ancestor of Odin.

The Anglo-Saxon royal genealogies are a collection of the genealogies of five pre-Viking kingdoms: Bernicia, Deira, Kent, East Anglia, and Mercia. Based on genealogical traditions of the 8th century, these documents are a product of the 9th century.
They are based on the report by Bede, according to whose Ecclesiastical History of the English People (completed in or before 731)
The two first commanders are said to have been Hengest and Horsa ... They were the sons of Victgilsus, whose father was Vecta, son of Woden; from whose stock the royal race of many provinces deduce their original.
By the time of the compilation of the Historia Brittonum (ca. 830), Godwulf is introduced as an ancestor of Woden's.
The full genealogy is presented in the Anglo-Saxon Chronicle, composed during the reign of Alfred the Great,
The genealogy of the kings of Wessex was added to this tradition at a later date, in the 10th century.
The 9th-century Anglo-Saxon genealogical tradition was perused by Snorri Sturluson, who in the 13th century wrote his Prologue to the Prose Edda.
