Mr Frederick William Pengelly was born in Calstock, Cornwall, England in the closing months of 1892, later being baptised on 2 December that year.
He was the eldest child of William John Pengelly (b. 1868), a tin miner, and Sarah Jane Eva (b. 1873), both natives of Calstock who were married in the closing months of 1891.
He had three siblings: William James (1895-1967), Lilian Beatrice (1898-1957, later Mrs Samuel James) and Russell Charles (1900-1902).
He appears on the 1901 census living at Todworthy in Calstock. His father died aged 33 before the close of the year and hard on the heels of his loss came the death of the baby of the family, Russell, who died in early 1902 having not reached his second birthday.
His mother remarried in 1904 to Silas George Reynolds (1882-1958), a granite quarryman, and from this union Frederick gained three half-siblings: Doris Gwendoline (1905-1977, later Mrs Frederick Howell), Silas George (1906-1961) and Winifred Eva (1907-1987, later Mrs Frederick Ephraim Mortimore).The family are shown on the 1911 census living at Chilsworthy Beam in Gunnislake, Cornwall but Fred was not listed with them and his whereabouts at the time are not clear. He, like his father, also worked as a miner.
Originally planning to travel on another steamer but forced to switch due to the ongoing coal strike, Frederick boarded the Titanic in Southampton as a second class passenger on 10 April 1912 (ticket number 28665 which cost £10, 10s) and he was travelling with three friends, William Ware and the Gale brothers, Harry and Shadrach. His intended destination was to his step-father, Silas George Reynolds in Butte, Montana where it is believed he was intent in working in the mines.
Frederick Pengelly died in the sinking and his body, if recovered, was never identified.
His mother Sarah Jane died in Cornwall in 1956 whilst stepfather died in Lamerton, Devon on 13 August 1958.
His brother William, a stonemason, later emigrated and settled in Michigan where he worked in an auto factory, was married and had two daughters. He died in San Bernardino, California on 23 April 1967.
