Nothing is known about the background of 12th century Simon of Dunblane, or Bishop of Dunblane as there are a number of Simons described from that era including Symon de Liberatione, Sion son of Mac Bethad, and Simon de Tosny.
Simon (d. 1194  1198) is the third known 12th century Bishop of Dunblane. Nothing is known of Simon's background as there are numerous Simons in Scotland in this period, both native and foreign. There is a Symon de Liberatione who witnessed a charter of King William the Lion and whom Watt and Murray suggested may have been the later Bishop of Dunblane, while there was in the same decade a local landholder and ecclesiastical patron in the diocese of Dunblane called Simon son of Mac Bethad. Simon's name occurs as Bishop of Dunblane alongside Simon de Tosny, Bishop of Moray, and Hugh, Bishop of St Andrews, in a charter dated to 1178, though Watt and Murray believed at this stage he was only bishop-elect.
