Thank you.
My major source for these dates is Scotland's People. I have also used ancestry and findmypast.
His name is Robert Nicol MASSON dob 17 August 1871 at Shore Street Fraserburgh.
His parents were John Masson, Fisherman, and Elizabeth Masson m.s. Nicol. The family was living at 10 Duke Street Fraserburgh for the 1871 census (before his birth). They were at 10 Seagate, Montrose, Angus, Scotland in 1881 as Mason - no mention of Robert. not found in census between 1881 and 1911.
His death is recorded at 22 December 1952 at 71 Castle Street Montrose. Cause of death shown as myocardial degeneration, chronic bronchitis. He is shown as a retired dock labourer, unmarried. Informant shown as W Masson (William Young Masson), his brother - address given is same as on his death registration of 1955.
