Thor of Tranent

[3] In a charter issued at Stirling granting a salt pan to Kelso Abbey in 1143, he appeared as Tor vicecomite, Thor the Sheriff.

[5] Appearing once more as "sheriff", at an uncertain point between 1143 and 1147, he was witness to a royal grant issued at Edinburgh of a toft in the burgh of Haddington, East Lothian, to Dunfermline Abbey.

[9] He is almost certainly the Durandus vicecomes, mentioned in two charters dating between 1140 and 1150, issued by king David and his son Earl Henry, granting the land of Clerchetun (i.e. Clerkington) to the church of St Mary of Haddington.

It was witnessed by William, Bishop of Moray, Osbern, Abbot of Jedburgh, Thor, Archdeacon of Lothian, Aiulf (Æþelwulf), Dean of Lothian, Nicholas, royal clerk (future Chamberlain of Scotland), as well as by Thor's own seneschal Gille Míchéil, and the lesser known figures Neis flius Chiluni, Eadmund son of Forn, Bernard son of Tocce, Eadmund of "Fazeside" and perhaps a man called "Alden".

[16] William is also known to have granted the church of Kirkintilloch in Clydesdale to Cambuskenneth Abbey, suggesting he shared in the fruits of the family's expansion into that western region.

[18] Through some unknown mechanism, in William the Lion's reign the land of Tranent was under the control of the incoming de Quincy family.
