Samuel Francis Webb was born in Salford, Manchester, Lancashire ¹, England on 24 November 1883.

He was the son of Bristol, Gloucestershire-natives Frederick Charles Webb (b. 1860), a chair maker, and Elizabeth Raby (b. 1864) who had married in Manchester in 1883 around the time of his birth.

He was apparently raised in Bristol and the surrounding area by his grandparents Samuel Webb (1838-1909), also a chair maker, and Susan, née Roberts (1837-1902). He was listed with them on the 1891 and 1901 censuses at 2 Clift Place, Weston in Gordano, Somerset. On the latter record he was described as a printer. Following the death of his grandparents and by the time of the 1911 census Samuel was listed as living with an uncle and aunt, William and Mary Ann Burnell, at 27 Lancaster Street, Bristol and he was described as an unmarried colliery hewer. He seemingly went to sea shortly after and worked on the Olympic.

When he signed on to the Titanic, on 6 April 1912, he gave his local address as the Sailors' Home, (Southampton) and his previous ship as the Olympic. As a trimmer he could expect to earn monthly wages of £5, 10s.

Samuel Webb died in the sinking. His body, if recovered, was never identified.
