Bertie William Lacey was born in Colchester, Essex 1, England in the second quarter of 1892.
He was the son of Edward Lacey (b. 1859 in Newark, Nottinghamshire) and Clara Adelaide Burch (b. 1859 in Ipswich, Suffolk). The couple were married in Colchester in 1885 and went on to have seven children: Minna Elizabeth (b. 1886), Edward Charles (b. 1889), Charles (b. 1890), Bertie (b. 1892), Dorothy Lilian (b. 1895), Evelyn Victoria (b. 1897) and May Clara (b. 1903).
On the 1891 census, taken the year prior to his birth, Bertie's family are listed as living at 25 Sussex Mews, St Mary at the Walls, Essex and his father was described as a groom and coachman. The family moved to Hampshire around 1894, settling at first in Netley followed by Shirley, Southampton. They are listed on the 1901 census living at Mason's Avenue (?), South Stoneham. After spending time living in Swaythling, Hampshire, the family made another move, this time to Salisbury, Wiltshire and are listed on the 1911 census living there at 22 Southampton Road, New Sarum. Bertie is not listed with his family but is listed as a boarder at 42 Northernhay Street, Exeter, Devon and is described as an unmarried waiter.
When he signed-on to the Titanic, on 4 April 1912, he gave his address as 26 Southampton Road, Salisbury. The Titanic was his first ship. As a second class steward he received monthly wages of £3, 15s.
