David "George" Gregory was born in Fawley, Hampshire, England in early 1869. He was the son of Joshua Gregory (b. 1826 1), a razor grinder, and Elizabeth Cooper (b. 1839). Both his parents hailed from Hampshire and had married in 1859. His father may have been married previously and had a son named Adam (b. 1851). The circumstances of this arrangement are not clear.
Sarah (b. 1861), Fanny (b. 1864), Joshua (b. 1866), May (b. 1872), William (b. 1874), Hannah (b. 1877), twins Eliza and Emma (b. 1879) and Arthur (b. 1880).
David first appears on the 1871 census whilst living with his family at Hill Top, Denny Lodge, New Forest, Hampshire. By the time of the 1881 census David's family were listed as living at Hythe Common in Fawley, his father now described as a tinker. David is not present and is listed elsewhere as an inmate at "Hants Reformatory," a juvenile correctional facility. David (or George as he was sometimes known) may have had further brushes with the law for felony and larceny.
His mother died in 1882. His father, who died in 1911, shows up on both the 1891 and 1901 census records living at Gilmore Pond, Sway, Lymington, described as a hawker and pedlar in the former. David would be absent, for reasons unknown from both records.
David shows up on the 1911 census living as a boarder at 32 Dock Street, St Mary, Southampton and is described as a ship's greaser and as unmarried.
When he signed on to the Titanic, on 6 April 1912, David gave his address as 30 Floating Bridge Road, (Southampton). His previous ship had been the Oruba. As a greaser he would earn monthly wages of £6, 10s.
David Gregory died in the sinking. His body, if recovered, was never identified.
