Mr Reginald Ivan Pacey, 17, was born in Southampton, Hampshire, on 22 October, 1894. He was the son of Thomas Pacey (1861-1932) and Kate Susanna (nee Roberts, 1863-1940). At the time of his birth, his father was a Shipping Time Keeper. He had seven siblings.
On the 1901 Census, 6-year-old Reginald was living at 27 Richmond Street, Southampton, with his parents (Thomas was listed as a Quay Foreman Labourer) and elder sisters Gertrude Ruby (14, a Mother’s Help), Edith Lilian (13) and Alma Violet (11). His brother, Thomas Hillman, had recently died, aged 8.
He attended a private boarding school at 27 Church Street, Romsey (probably Osborne House School), and it was here that he was listed at the time of the 1911 census. Thomas was now a Stevedore, and Gertrude had left home, having married the previous year. Edith and Alma were both Shorthand Typists and they had some more younger siblings: Lorna Alexandra (10), Leonard Archibald (8) and Edna Patricia (6).When he signed-on to the Titanic, on 9 April, 1912, he gave his address as the family home of Cambridge Villa,  Milbrook Road, (Southampton). The Titanic was his first ship. As a lift steward, he received wages of £3 15s.
Pacey died in the sinking. His body, if recovered, was never identified.
