From the 1939 Register, Robert L. Parker was living at 45 St. James Road. He was born on 14th October 1895 and was a Furniture Warehouseman. He lived with his wife Helen, born 16th December 1894, and their son Robert E., born 15th April 1920, a turner in an engineering factory. In the 1964 and 1965 electoral registers Robert and Helen are still at this address.
His granddaughter said in October 2019 that he served in WW2 and lived in St James Road.
However while there aren’t any records online for Robert Linthorn Parker, there are some for Robert Parker and R.L. Parker, but at present it is not possible to see which of these he is.
He died in the first quarter of 1981, and the registration district was Wandsworth.
