Thor Longus or Thor the Long (fl. c. 1113 x 1124) is an early 12th century Anglo-Saxon noble associated with Roxburghshire, a culturally English territory ruled by the Scottish king from the 11th-century onwards. A charter dating between 1107x1113 and 1124 claims that Thor the Long founded Ednam, previously a deserted waste granted to him by King Edgar of Scotland.[1]
Ednam lies close to the Northumberland border with Roxburghshire. It states that he repopulated the settlement with his own followers and a church.[1] The charter grants the church to the monks of St Cuthbert.[1] There survives the notice of this grant given by Thor to his lord Earl David (future David I of Scotland), as well as Earl David's confirmation of the same grant.[2]
Thor had a brother named Leofwine, mentioned in Thor's charter as requiring "redemption".[3] Leofwine "the monk" was commemorated in the Martyrology of the Durham Cantor's book for June 2 (day of death), and in the same source Thor Longus was commemorated for May 14.[4] The year of his death and descendants are not known, but Ednam appears in the crown's hand in 1136.[5]
