1360 pro cariagio ix damplade de la Lendyng
1404 In cariagio xx damlad dictorum lapidum ... usque Ebor. per navem. The prefix has no obvious meaning but the connection may be with the Archbishop since ‘dam’ and ‘damp’ were used in that period as a courtesy title for a knight, lord or bishop. The OED records c.1489 ‘Damp bysshop ye be welcom’. Salzman says the term is peculiar to Yorkshire and seems to have been equivalent to ten tons.
