Harry first appears on the 1881 census when he and his family were living at 1 King Street in Portsea, Hampshire. and his father was described as a sick berth steward in the Royal Navy. He and his family had shifted to 24 Mayo (?) Street, Portsea by the time of the 1891 census. His father died sometime after this and by the time of the 1901 census his mother was a widow and now living in Herefordshire at 8 Horns Mill Cottages in Hertford. Harry was absent and perhaps already at sea. His mother was remarried later in 1901 to Henry Carlton Whiting (b. 1876 in Sawston, Cambridgeshire). She settled in Hertfordshire and died in 1943.
Harry had been married in 1905 to Ethel Jack Cross (b. 8 January 1884 in Norfolk) and the couple initially had three children: Henry Jack (1906-1999), Willis James (1907-1982), Kathleen Ethel (1910-1932) and the family are listed on the 1911 census living at 114 Lyon Street, Southampton and Harry was described as a bedroom steward for the White Star Line. Harry and his wife would have another son on 11 April 1912, Ernest Hope (d. 2001).
When he signed-on to the Titanic, on 4 April 1912, Harry gave his address as 114 Lyon Street, (Southampton). His last ship had been the Olympic. As a bedroom steward he received monthly wages of £3, 15s.
