My intention was to try to find out if The Old Cottage and Stanmore Cottage were the same place. No luck with that so far but I did find out a bit about Louie and George.
Firstly, I found a newspaper report in the Sussex Agricultural Express 27 August 1943. It mentions Mr. George Kennard of Stanmer (not Stanmore) Cottage, Dane Road, Seaford had received news that his son, Pte. John Kennard, was reported missing from operations off Sicily. From your last post I see your mother would have been there when he received this news in 1943.
A bit more digging revealed that John was the son of George Kennard and his first wife Elsie Clayton. He divorced Elsie in 1937 and in 1938 he married Frances Louie Wall. His address at the time was The Creamery, Seaford.
Still trying to find out if The Old Cottage and Stanmer/Stanmore Cottage were the same place
