Thor Longus

c. 1113×1124) was an early 12th-century Anglo-Saxon noble associated with Roxburghshire, a culturally Northumbrian and Brythonic Cumbric Celtic (Carvetii, Brigantes, Selgovae) territory ruled by the Scottish king from the 11th-century onwards.

A charter dating between 1107×1113 and 1124 claims that Thor the Long founded Ednam, previously a deserted waste granted to him by King Edgar of Scotland.

The charter states that he repopulated the settlement with his own followers and built a church.

[1] The charter grants the church to the monks of St Cuthbert.

[4] The year of his death and descendants are not known, but Ednam appears to have been transferred into the Crown's hands by 1136,[5] so he can be presumed dead by that date.
