Alonzo was the son of George Robert and Ellen Aubrey (née Hood).
His father George Robert (also Robert) Aubrey was born in Wisbech, Cambridgeshire, in about 1854. His mother Ellen Hood was born in Old Basford in 1855, the daughter of George and Mary Ann Hood. She was baptised at Basford St Leodegarius on 12 May 1856.
George and Ellen were married in 1877 (A/M/J Basford, surname Aubury). According to the information George provided on the 1911 Census, he and his wife had had five children of whom four survived. Three children have been identified from the Census, all born in Basford: George William b. 16 March 1878 (A/M/J Basford, Aubury); Priscilla Louisa b. 4 June 1880 (J/A/S Basford, Aubery) and Alonzo Robert b. 1883 (A/M/J Basford, Aubery). The child who died young may have been Thomas Burnham Aubrey b. 1886 (O/N/D Basford) who died in 1889 (A/M/J Basford). However, on the 1901 Census George and Ellen were recorded caring for a 'nurse child', Clara Burdell aged 7 (b. 2 September 1893, O/N/D Nottingham, mother's maiden name not recorded), who in 1911 was still living with the family but described as Clara Aubrey (17), status daughter.
George was a gas works labourer with Nottingham Corporation, probably at Basford gas works. In 1881 he and Ellen and their two children, George (3) and Priscilla (under 1yr), were living at 7 Monsall Street, Basford.
The family had moved to 1 Ekowe Street by 1891 and was living at the same address in 1901: George, Ellen, George jr. who also worked at the Corporation gas works, Priscilla an upholsterer (wicker work), Alonzo (17) a wicker worker and Clara Burdell (7) nurse child.
By 1911 George (56) and Ellen (55) were living at 4 East Rowe Street, Nottingham. Only Alonzo, a basket maker, and Clara (Aubrey), an upholsterer, were still living at home.
Alonzo's father, George Robert, died in 1930 (A/JS Nottingham) and his mother Ellen on 8 January 1933 aged 77.
Alonzo married Ellen Mahala Plackett at Radford parish church on 17 October 1912. His wife Ellen was born on 25 October 1885, the daughter of Louis Alexander Plunkett and his wife Bertha (née Draper). In 1911 Ellen was living with her parents and working as a robe and blouse cutter.
Alonzo and Ellen had two sons, George Robert b. 30 April 1913 and John Urban b. 2 May 1916. They were living at 2 Delta Street, Old Basford, in 1915.
Ellen married secondly Henry E Taylor (b. 15 February 1880) in 1922. In 1939 when the England & Wales Register was compiled, she and Henry, a locomotive engine driver, were living in Nottingham, with her son John Urban, who probably worked for the Corporation's gas works, her sister Annie Elizabeth Plunkett (b. 23 April 1890) a lace worker, and her unmarried brother George William Plunkett (b. 14 March 1893) a gown manufacturer. Ellen died on 19 July 1975; she was then living on Cherry Orchard Mount, Bestwood Park, Nottingham.
Alonzo's son George Robert married Dorothy Elliott (b. 18 May 1912) in 1938 (O/N/D Basford). In 1939 they were living on Minver Crescent, Nottingham; he was a motor spinner (petrol and diesel). George died in 2002 (J/F/M Nottingham).
His second son, John Urban, was living with his mother and her husband in 1939. He may have married Rose A Smith in 1949 (A/M/J Southwark London). He later lived in Rowe Gardens, Nottingham NG6; the electoral register (2003-2010) records two other occupants, Stephen Aubery (probably Stephen J. b. 1957 J/F/M Nottingham, mother's maiden name Smith) and Ruth Aubrey. John died on 10 August 2010; he was still living in Rowe Gardens.
Of Alonzo's siblings:
George William married Emma Badder (b. 21 December 1879) in 1907 (O/N/D Nottingham); there were probably no children of the marriage. In 1911 they were living at 305 Radford Road, Hyson Green, Nottingham, with his wife's widowed mother, Emma Badder. George was a painter (gas meters) and his wife a confectioner (at home). They were still living at the same address in 1939; George was a shopkeeper (sweets and tobacco). He died on 25 March 1963; he was then living in Clifton.
Priscilla Louisa married Thomas Brown (b. 26 March 1879) in 1902 (J/F/M Nottingham). In 1911 they were living on Lincoln Street, Basford; he was a sweep on his own account and Priscilla was still working as an upholsterer. Priscilla died in 1966 (O/N/D Nottingham).
