M. de Dunblan
is the way the first known Bishop of Dunblane
is written in a copy of a papal bull
of Pope Adrian IV
preserved in England
; the bull dates to 1155.
The papal bull was addressed to the bishops of Scotland ordering them to submit to the metropolitan authority of the Archbishop of York; the copyist made two other mistakes in the initials of bishops, so it is not totally reliable.
Cockburn speculated that M. might stand for Máel Ísu; it is very unlikely that M. was a mistake for La., standing for Laurence the successor of M. at Dunblane.
