To add to the previous notes. A tor is a door or gate(way) in German, Tur zu bitte as a German Larry Grayson would have said. It sometimes relates to the the gateway of a hilltop fortification. The name tor - or torr - as in the the Peak district and Exmoor/Dartmoor is possibly derived from this. As to a Scandinavian Tor connection I have found absolutely no Torr family ties to this part of the world in many years researching the family.
