Mr Leonard Lisle Oliver White was born in Lismore, New South Wales, Australia in 1880, the son of Robert and Elizabeth White. Other details about his early life remain unknown.

He was married in Southampton, England in the latter months of 1911 to Alice Maud Mason (b. 3 September 1882), a native of that city. 

Alice Mason was the daughter of Alfred Mason, an agricultural labourer, and Elizabeth, née Ember. She, like several of her sisters, worked as a head laundress at the time of her marriage. She was shown on the 1911 census as a single woman living with her widowed mother at 248 Romsey Road, Shirley, Southampton. Leonard and Alice would have no children.

Leonard was on board the Titanic for her delivery trip from Belfast to Southampton and when he signed-on again in Southampton on 4 April 1912 he gave his address as 248 Romsey Road, Southampton. His previous ship had been the Osterley and as a saloon steward he received monthly wages of £3, 15s.

Leonard White died in the sinking and his body, if recovered, was never identified. The following death notice appeared in The Hampshire Independent (unknown date):

WHITE -- April 15th, at sea on S.S. Titanic, Leonard Lisle Oliver White, age 31, the dearly beloved husband of Alice Maud White. Gone but not forgotten. Australian papers please copy.

His widow Alice was remarried in 1917, becoming Mrs Edmund George Tindall (1891-1962). Her new husband, nearly a decade her junior, hailed from Scarborough, Yorkshire and worked as a grocer and later in an electrical store. The couple had only one child, a daughter named Vera Maud (later Mrs Cedric Morris Edwards) who was born on 27 March 1919.

Alice died in Southampton on 25 August 1957, just shy of her 75th birthday. Her widower Edmund died in 1962 and her daughter Vera in Southampton in July 2006.
