Mr Alexander Milne Cairns was born on 19 April 1883 in Kinfauns, Perthshire, Scotland.
He was the son of William James Cairns (b. 1843) , an agricultural labourer, and Margaret Milne (b. 1840), both natives of Forfarshire who had married in Kirriemuir on 19 March 1864.
He had eleven siblings: John (1864-1894), Betsy Findlay (b. 1866), Andrew (1868-1934), James Milne (1870-1935), Margaret Shrubsole (1872-1920, later Marks), William (1874-1881), Jessie McRae (1876-1952), Jane (1878-1965), Joan (1879-1898), David Murray (1881-1942) and Charlotte Carolina Shrubshole (1886-1960). His brother Andrew had been born on 15 April 1868.
In the years prior to Alexander's birth his father had worked as a railway labourer and the family appear on the 1881 census living at Old Toll House in Rescobie, Forfarshire. Alexander first appears on the 1891 census when he and his family are residing at Cottar House in Littleton, Longforgan, Perthshire. When the 1901 census was conducted the family were residents of Seggieden Porter Lodge in Kinfauns, his father now working as an estate labourer, but Alexander was not present at his whereabouts at the time are unknown.
He and his brothers James and William later emigrated around 1905 and settled in Philadelphia where they worked as Lace weavers, showing up on the 1910 census as boarders at 2918 Sixth Street. Exactly when Cairns came into the employ of William Ernest Carter is not known.
Cairns boarded the Titanic at Southampton as a first class passenger, travelling in the Carter entourage and on the same ticket as Augusta Serreplaà, the Carters' French maid (ticket number 113798 which cost £31). Whilst aboard he occupied cabin B86.
Alexander lost his life in the sinking and his body, if recovered, was never identified.
