Miss Mabel Elvina Martin was born at 21 Goldsmith Road in Acton, London, England on 18 March 1892 and was baptised on 16 October that same year in St Dunstan's Church.
She was the daughter of London-born Alfred Thomas Martin (b. circa 1863), a banker's clerk, and Alice Emily Bulley (b. circa 1867) of Maldon, Essex. Her parents had been married in Acton on 12 October 1887 with both their addresses being stated as Grove Road, Acton.
She had an elder sister, Eva Marguerite (1889-1972) who appeared with her parents on the 1891 census as residents of 21 Goldsmith Road, Acton. Little else is known about Mabel's early or familial life.
On the 1911 census Mabel is shown working and living at the Tavistock Hotel, Covent Garden, West London as a bookkeeper.
When she signed-on to the Titanic on 6 April 1912 Miss Martin gave her address as 1 Apsley Villa, Horn Lane, Acton, London. The Titanic was her first working sea voyage and she was one of two female cashiers in Gatti's Titanic restaurant, the other being Ruth Bowker. Her discharge book describes her as standing at 5' 4" and with brown hair and eyes and a dark complexion.
Miss Martin was rescued in lifeboat 6 alongside Ruth Bowker and it has been said that she was among the women in that boat who helped row. She was not required to give evidence to either the US or British Inquiries into the disaster.
Mabel was married in 1914 to Francesco Rafaelle Odone Albertella who was born 1 September 1891 in Westminster, the son of Italian immigrants Angelo Albertella and Genevia Raffaeli. His family were connected in the restaurant business and he and Mabel went on to run their own restaurant (the Rendez-vous?); by the time of the 1939 British register their address was 255 Richmond Road, Kingston, Surrey and where Mabel would live for the rest of her life.
Mabel and Francesco had one child, a daughter Joan, who was born in Brighton in 1921.
Mabel Martin was involved in a motorcycling accident and died in Kingston Hospital on 2 April 1960 aged 68. She was buried on 9 April in St Andrew's Church, Ham, Surrey. She left an estate valued at £274, 17s, 11d to her husband, who himself passed away on 11 June 1974. Her daughter Joan was married in 1952 to George C. Lewis and lived for many years in Woking, Surrey, retaining several items belonging to her mother connected to Titanic, including her discharge book. These items were placed up for auction in 2017.
