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 (b. 1847), an engine fitter, and Elizabeth Wood (b. 1845) who had married in Yorkshire in 1868. He had eight known siblings: twins Charles Herbert and Jenny Wood (b. 1869), Edmund (b. 1871), Cate (b. 1872), 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 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 (b. 1905), Marjorie Wood (1907-1995) and Doreen Abernethy (b. 1910). The family appear on the 1911 census of Ireland living at 11 Sunbury Avenue, Pottinger, east Belfast and Anthony is described as a foreman engine fitter.
Anthony 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. He, like the rest of his counterparts, died in the sinking. His body, if recovered, was never identified.
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 aged 72. She is buried in Roselawn Cemetery, Belfast.
