Randolph, Earl of Moray - arms puzzle

At:

is the coat of arms of Alexander Mylne (1474-1548/9), Abbot of Cambuskenneth. But these are the arms of Randolph, Earl of Moray. Any ideas as yo why Alexander Mylne would use the arms of Randolph?

The arms at the top are those of Patrick Dunbar, Abbot of Cambuskenneth.

Many thanks for your reply.

Do you have dates for him? He does not appear under that name in the list of abbots at:

http://en.wikipedia.org/wiki/Abbot_of_Cambuskenneth

Also, the text under the illustration says 'Alexander Cambuskenneth' (modern spelling given), not Patrick. Does this text refer to something other than the illustration above it do you think? If so, what?
