Many thanks for all your replies, and the clipping and transcription.
If you go back to the original clipping I posted, you can see that there are 2 very similar entries.
This one found for 1629 - John Cochrane in Strahaven , par of Evindall', is on the list 4 entries further down from the one 'John Cochrane parochinar of Strathavene II 46'.
It seems to me they would be 2 different people, or they would not be separately listed.
There were scores of Cochranes around Strathaven, many of them called John unfortunately!
So back to my original puzzle.
Does anybody have any clue to these 'folios' and Volumes, or is my best bet to contact NRS if and when they might be open again?
Thanks for all your time
