Henry was the son of Henry Thompson and Ada Blatherwick.
Henry and Ada might not have married as no record of a marriage has yet been traced although Ada's name was given on the 1911 Census as 'Ada Blatherwick.' The registrations of the births of their eight surviving children who were named on the census gave the children's second names and surnames as either 'Thompson Blatherwick' or 'T Blatherwick.' The eight children named on the 1911 Census were: Frank Henry b. 1894, Robert b. 1895, Henry b. 14 November 1897, Arthur b. 1900, John b. 1902, George b. 1905, Leonard b. 1907 and Ada Sarah b. 1910. All the children were born in Nottingham.
Another daughter may have been born after 1911 as there is a registration of the birth of a Gertrude T Blatherwick, mother's maiden name Blatherwick, in 1912. Gertrude died in 1918 aged 6.
Henry and Ada were living at 12 Leicester Street, St Ann's, in 1901 with their four children, Frank (6), Robert (5), Henry 3) and Arthur (11 months). Also in the household was a lodger, Eliza Sansom (70). On this census Ada and the children had the surname Thompson and Ada was described as Henry's wife.
By 1911 the family had moved to 23 Edwin Street, Nottingham. Henry Thompson (54), a bobbin and carriage hand (lace machine), completed the census with the information that he was married (18 years) and the eight children in his household were his sons and daughter. He and Ada had had nine children of whom eight survived. The children's second names and surnames were given as 'Blatherwick Thompson'. Frank was a coal miner at Wollaton pit, Robert was working in the warehouse of a paper manufacturer, Henry worked for the post office, Arthur, John (8) and George (6) were at school while the two youngest children, Leonard (3) and Ada (1), were under school age.
It is probable that Henry Thompson died at the end of 1913 or early in 1914 as there is the death of a Henry Thompson (b. abt. 1856) was registered in the first quarter of 1914.
Ada was living at 31 Edwin Street when she was notified of her son's death in October 1914.
Henry's younger brother, Arthur (Blatherwick), enlisted in the Sherwood Foresters on 2 September 1915; he was 15 years old but claimed to be 19 years 4 months. He served at home until 10 March 1916 (196 days) when he was discharged 'having made a misstatement as to age on enlistment vide para 392 Kings Regulations Auth. OIC Infantry Records Litchfield, 10 March 1916.' He had named his mother, Ada (Blatherwick) of 31 Edwin Street, Nottingham, as his next of kin.
Ada probably died at the age of 54 in 1927.
