Henry James Crabb was born in mid-1889 in Lambeth, London, England. He was the son of Richard William Crabb (1855-1926) and Mary Ann (b. 1853): his parents were natives of Alderney and Guernsey in the Channel Islands, respectively and were married around 1877.
On the 1891 census the family are resident at 53 Haslington (?) Street, Kennington, Lambeth and Richard Crabb is described as a railway porter. Henry's siblings at the time are William (b. 1878), Ernest (b. 1880) and Edith May (b. 1885). They are still present at the same address for the 1901 census (minus his sister Edith). By the time of the 1911 census the family have moved to 101 Firgrove Road, Southampton. All of the children are absent. The census indicates that Richard and Mary Ann Crabb had a total of 6 children, 4 living past infancy.
When Henry signed on to the Titanic as a trimmer, he gave his address as 101 Firgrove Road, Southampton. As a trimmer he could expect to receive wage of £5 10s per month. His previous ship had been the Olympic.
Henry Crabb was lost in the Titanic disaster. His body, if recovered, was never identified.
