Harold was the son of William and Kate Catherine Butler (née Cooper).
Both his parents were born in Nottingham, William in about 1866 and Kate in 1869. They were married in 1887 and had 12 children, five of whom died in infancy or childhood. Their seven surviving children were: Harold b. 1891, William b. 1895, Claude b. 1899, Sidney b. 1901, Dora birth registered 1903 (J/F/M), Ronald b. 1905 and Leslie b. abt 1909. They were born in either Sneinton or St Ann's.
Shortly before Harold's birth, William, a bricklayer's labourer, and Kate, a winder, were living at Thoresby Street, Sneinton in 1891, but had moved to 23 Norland Road, St Ann's, by 1901.
The family was living at 19 Providence Street, Corporation Road, St Ann's, in 1911: William, Kate and their seven children, Harold a cabinet maker, William a bricklayer, Claude, Sidney, Dora and Ronald who were school age and Leslie.

In 1939 when the England & Wales Register was compiled, Jenny and her son John H Butler were living with her widowed father, Robert Derrick (d. 1947), at 60 Corporation Road. Harold and Jenny's daughter, Jenny, had married Joseph W Evans in 1937 and they and their daughter were also living in Nottingham.
