She was initially found as the executor for her mother in 1958 and then with her mother in the 1939 census, but in neither record was it absolutely clear that she was the daughter.  The latter record gave a birth date which did not correspond with any British birth.  However there is an Army birth in South Africa that could well be hers:

First name(s) VIOLET
Last name CLOSE
Birth year 1905
Place TEMPE
Country SOUTH AFRICA
Page 698
Record source GRO Army Birth Indices (1881 to 1965)
Record set British nationals armed forces births 1761-2005

However she was single in 1939 and died with the sme name in 1987 so seems never to have married or had children.
