 John Cameron (of the Lochiel Campbells) became Bishop of Glasgow - and made the Prebendaries of Cambuslang Chancellors of the Cathedral - and went on to hold all the Great Offices of State.David Beaton probably never even visited his Parish on his way up the ladder to become the Cardinal later murdered by soldiers supporting the Reformation in Scotland.Both Cameron and Beaton were members of the Scottish aristocracy, as were a number of other Rectors and Prebendaries - such as Lord Claud Hamilton - and the "English Cleric" mentioned below no doubt accompanied the many Anglo-Norman adventurers who came to Scotland at the time.
