Thank you for that information Graham. I am interested in Orkney during the War so following this lead up might lead me to Ron Douglas.
To Steviebyday, thank you again for the information on Ron Douglas and I am sure that this is the person I am looking for, but I have just been in touch with the family of Ronald Alexander Douglas, born Camberwell, 1920, and they say that the Ronald Alexander Douglas in their family was not posted to Orkney as far as they are aware, and is not the gentleman in uniform in the photos that I posted on Ancestry. He is wearing the uniform of the Orkney and Shetland Defence Forces. Can you advise me where on the National Archives website information on army personnel posted to Orkney as part of the Orkney and Shetland Defence Forces can be found. There must be another Ron Douglas who was posted there 1944-1947. Many thanks, once again for your efforts to help me.
