One or other of the dates in the title is presumably an error. 'J.R.M.' has not been identified, but the material was collected and the manuscript written by the Reverend John Norman MacDonald, Minister of Harris. Notes on folios 6 verso and 50 verso, the latter dated 'Oct. 30th 1854', are signed with his initials. There are also some notes in pencil, in the hand of the Reverend A J Macdonald, Killearnan.
