Murdo Mackay gave evidence to Lord Napier's Commission at Ness on 7 June 1883.
The 1871 census shows Murdo as a wool weaver in Cross (Barvas), aged 45. He is living with his daughter Christina (27), her husband Norman (20) and their daughter Catherine (5 months old). I have been unable to trace Murdo in earlier or later censuses. It is possible that this Murdo Mckay supposedly died on North Rona in February 1885, aged 57. He was married to Ann Morrison.
