Thomas Herbert Weatherston was born in Liverpool, Lancashire, England in the summer of 1887. He was the son of Thomas Weatherston (1850-1927) and Jessie Ann Jacks (1862-1923).
His father hailed from Lauden, Berwickshire, Scotland and married Jessie Ann Jacks, a native of Woolwich, Kent, in Liverpool in 1886. At the time of Thomas' baptism, which took place in All Saints Church, Stonecroft, Liverpool on 17 July 1887, his father was described as a clerk and they were resident at Buxton Terrace in that city. He had two brothers, Donald Alexander (b. 1888) and Leslie Henry Parry (b. 1895).
Thomas first appears on the 1891 census with his family living at 11 Holly Grove, Litherland, Lancashire and his father was described as a manager. They would be at the same address by the time of the 1901 census and his father would now be described as a commissioner agent living on his own means. Thomas and his brother Donald would be listed as visitors at 45 Heaton Moor Road, Heaton Norris, Cheshire on the 1911 census, the home of a Mr John and Edith Hopwood. Both he and his brothers were described as stewards. His parents and younger brother Leslie were listed elsewhere, still at 11 Holly Grove.
Thomas was on board the Titanic for her delivery trip from Belfast to Southampton. When he signed-on again, in Southampton, on 6 April 1912, he gave his address as 5 Kenilworth Road, (Southampton), a lodgings address. As a first class saloon steward he received monthly wages of £3 15s. His last ship had been the Olympic.
Weatherston, who was unmarried, died in the sinking. His body, if recovered, was never identified. His effects, worth £103, 10s, were administered to his father on 7 June 1912. Both his parents remained in Liverpool and died in the 1920s.
His brother Donald later married and settled in New York. He died in Burlington, New Jersey in 1974. What became of his brother Leslie is uncertain.
