Harold Walker was the son of Herbert and Sarah Ann Walker (née Eden).
His father Herbert was born in about 1849 (d. 1910) at Derby and his mother Sarah Eden was born at Lenton in about 1851. They were married at Basford St Leodegarious in November 1872 and had six children: Thomas William b. 1873 d. 1911, Ruth b. 1874 and Horace b. 1878 d. 1902 who were born in Basford and Mary Louisa b. 1881, Kate b. 1883 and Harold b. 1886 who were born in Nottingham.
In 1881 Herbert, a lace maker and Sarah were living on Gadd Street, Nottingham, with their four children Thomas, Ruth, Horace and Lily (sic. probably Mary Louisa). They had moved to Mabel Street in Nottingham by 1891; Herbert was now working as a millwright pattern maker. With the exception of the eldest son, Thomas, all the children were in the home on the night of the census.
Herbert, a millwright, and Sarah were still living on Mabel Street in 1901. Only Mary a mantle assistant, Kate a lace warehouse assistant and Harold, an errand boy, were still living at home. Also in the household was Herbert and Sarah's grandson, Leonard Walker (5). Of their three other children, Thomas had married Agnes Jane Walker in 1895 and Ruth had married William Reddish in 1899. Horace had married Grace Maria Gains at Nottingham (Meadows) St Saviour in September 1900 and they were living in Carlton. Horace died in March 1902 aged 23 (buried Nottingham General Cemetery).
Herbert died in 1910 (O/N/D) aged about 61.
In 1911 his widow, Sarah, and their grandson Leonard, a grocer's assistant, were living on Beauvale Road, Meadows, with her married daughter Mary Louisa Brown and her husband Arthur, a flour carter (employer). Mary and Arthur had married in 1904 and later emigrated to Australia where they settled in Queensland.
Thomas and his wife and their four surviving children were living off Kirkewhite Street, Meadows, in 1911. Thomas died in April that year. Ruth Reddish and her husband William were living in Beeston, Nottingham, while Kate and Albert Steggles were living in West Bridgford, Nottingham.
Harold married Catherine (Kate) Smith (born April 1884, Aslockton) in 1908 at Nottingham. They had two children - Ernest born 21st September 1910 and Reginald born 20th April 1913. In 1911 they were living at 23 Spalding Road, Carlton, Nottingham. The family later lived at 30 Moreland Street, Meadow Lane, Nottingham.
