Mr Anthony Wood Frost was born in late 1873 in Hull, Yorkshire, England and he was later baptised on 26 January 1874 in Holy Trinity Church, Hull.
He was the son of George William Frost (1846-1918), an engine fitter, and Elizabeth Wood (b. 1845), natives of Hull and Lincolnshire, respectively who had married in Yorkshire on 24 November 1868.
He had nine known siblings: twins Charles Herbert and Jenny Wood (b. 1869), Edmund (b. 1871), Cate (b. 1872), Harold (b. 1877), Walter Stanley (b. 1878), Aaron (b. 1886), Septimus (b. 1884) and Annie (b. 1886).
He first appears on the 1881 census as a visitor at the home of his maternal aunt Harriet Frost at 1 Medley Street, Sculcoates, Yorkshire. His family moved to Belfast around this time where his father worked for Harland & Wolff and Anthony appears on the 1901 Irish census living at 12 Mount Street off the Ormeau Road in south Belfast, Co Down and he is described, like his father, as an engine fitter.
He was married in Belfast over the summer months of 1901 to Elizabeth "Lizzie" Jane Hamilton (b. 1874 in Co Antrim) and the couple had four children: Robert John Hamilton (1902-1986), Walter Stanley (1905-1985), Marjorie Wood (1907-1995, later Mrs Harry McCormick) and Doreen Abernethy (1910-1973, later Mrs Samuel Hamilton Dunlop). The family appear on the 1911 census of Ireland living at 11 Sunbury Avenue, Pottinger, east Belfast and Anthony was described as a foreman engine fitter.
In the service of Harland & Wolff for twenty-four years, Frost commenced work at Queen's Island as a machine boy on 4 January 1888 before being appointed apprentice fitter the following year. After completion of his apprenticeship in March 1894 he spent two years at sea to gain experience.
Following his return to the shipyard, he was promoted to leading hand in March 1901. When his father retired in 1907 young Frost succeeded him as outside foreman engineer. He had been in charge of the overhauls of the machinery aboard HMS Endymion and Hermes and during the trials of HMS Enchantress, Hibernia and Minotaur. He went on to oversee the installation of the plant aboard Olympic and Titanic. Described as one of the most energetic and capable foremen at Harland & Wolff and perhaps on the eve of a promotion, Frost was one of the nine-strong "guarantee group" of Harland and Wolff employees chosen to oversee the smooth running of the Titanic's maiden voyage.
Anthony Frost, like the rest of his counterparts, died in the sinking. His body, if recovered, was never identified.
His estate, valued at £254, were administered to his widow on 12 July 1912.
His widow Lizzie was never remarried and she remained in Belfast for the rest of her life. She later lived at 2 Hillcrest Gardens and died on 23 February 1961 and was later buried in Roselawn Cemetery, Belfast. Her last surviving child Marjorie died in Belfast on 17 July 1995.
