Joseph Henry Lamb was the son of Joseph and Sarah Lamb (née Rolling).
His father Joseph was born in 1857 at Hexham, Northumberland, the son of Francis Lamb, a miner, and his wife Mary (née Thompson), and baptised at the Allendale Chapelry, Ninebanks, on 12 July. His mother Sarah was born in York in 1856, the daughter of George Rolling, a gardener, and his wife Ann Elizabeth (née Ullyott). Sarah was baptised at St Mary Bishophill on 11 May 1856.
Joseph and Sarah were married in 1882 (reg. J/F/M Newcastle upon Tyne) and had four children who were born and baptised in Gateshead: Annie Jane birth registered 1883 (j/F/M) bap. 14 March; John George b. 1884 bap 4 November; Joseph Henry birth registered 1889 (J/F/M) bap. 16 January and Eleanor May b. 1892 bap. 15 June.
In 1891, nine years after their marriage, Joseph (33), a railway engine driver, and Sarah (34) were living on Harlington Street, Gateshead, with their three children, Annie (8), John (6) and Joseph (2). Their fourth child, Eleanor, was born the following year.
The family had moved to 8 Richardson Street, Heaton, Newcastle upon Tyne, by 1901. All four children were in the home on the night of the census: Annie of no occupation, John a brass finisher and Joseph and Eleanor who were school age.
The family had moved to Nottinghamshire by 1907 when the youngest child, Eleanor, died at about the age of 14 (reg. J/F/M Shardlow Derbyshire). The eldest child, Annie, died in 1911 (reg. J/F/M Shardlow) aged about 27.
John and Sarah were living at Park Road, Chilwell, Nottingham, in 1911; John was no longer working and Sarah was recorded on the census as head of household. Of their two surviving children, only John, a shawl maker, was still living at home, Joseph having joined the army in May 1908 and at the time of the census serving with the Sherwood Foresters at Crownhill Barracks in Plympton, Devon.
Joseph's parents were still living on Park Road, Chilwell, when he was killed in 1917.
His mother Sarah may have died in 1925 (reg. O/N/D Ripon West Riding) and Joseph in 1929 (reg. J/F/M Newcastle upon Tyne).
