Well. The paperwork sent through confirms that Colin Seale is not Robert. He went to England in 1939. They relate to a request to the High Commission to trace him. Colin had a daughter, Lorna, and a son, possibly two, as there was a reference to "Lorna's brothers" in one of the letters. The one brother mentioned is referred to as Gunner D Seale.
Lorna was born about 1930. She left India in 1948 to go to England, and to try and find her father. In the meantime she stayed with a Mr and Mrs RP Grant. (I'm not sure if they are related to George Grant who had married Hilda Seale in 1917).
Colin was located living with a Sergeant B Seale in Burniston Barracks, Scarborough. UK. Betty
