But is there any such Urvater for "England"?
They wanted Brutus for Britain, but England comes along later that classical times, from the Angles. Maybe that tribe derived itself from some mythic father, but I haven't come across it.
Starting searching on wikipedia - "Bede states that the Anglii, before coming to Great Britain, dwelt in a land called Angulus
, "which lies between the province of the Jutes and the Saxons, and remains unpopulated to this day."
But no Urvater by that name - "According to Anglo-Saxon legends recounted in Widsith and other sources such as Æthelweard (Chronicon), their earliest named ancestor was a culture-hero named Sceaf
, who was washed ashore as a child in an empty boat, bearing a sheaf of corn."
It seems improbable to think no one ever connected Anglus with the Angles or English peoples, but evidence remains elusive.
