Info from wiki: Jocelin (or Jocelyn) (died 1199) was a twelfth-century Cistercian monk and cleric who became the fourth Abbot of Melrose before becoming Bishop of Glasgow, Scotland. Jocelin appeared at King Henry's court in January 1176. This time church matters were on the agenda. When the Archbishop of York confronted Jocelin over the subordination of the bishopric of Glasgow to the archbishopric of York, Jocelin refused to acknowledge this part of the treaty, and presented him with the Papal Bull declaring Glasgow to be a "special daughter".
