These are my possible findings.
George Henry Shrimpton was born 1.1.1897. Birth registration does not show a mmn. Married jq 1927 Ethel Aylott.
George died 1972 dob 1.1.1897 (on 1939 register dob 31.12.1897.
Ethel died 1997 dob 27.9.1903 as per 1939 register.
George and Ethel had been living at 149/174 Fairbridge Road, Islington from 1934-1938. Only George is at this address in 1939, Ethel elsewhere.
A schools admission record entry dated 26.8.1901 for a George Shrimpton born 1.1.1897 records parent/guardian as George. The address given , 254 Tufnell Park Road.
Living at this address in 1901 census is a Beatrice Shrimpton, niece, unmarried born 1876 Kilburn whom I suspect is his mother.
Cannot find George though in 1901/11/21 census.
