Hi, Thankyou very much for your message, I have posted them everywhere I can think of and your the only one that has replied!
The trouble with Josephine was that the only remaining members of my family knew her when they were very little girls and so information is limited, also this particular Adams family were very poor letter writes which makes it a bit difficult. I do not know the name of the military family for whom she was a nanny, but I have written to my Aunt to find out where she was living before she went to Singapore, and from there I cantry and find the advert she answered for it will have the name of the family on, its a long straw, but I may be lucky!
Do you know if there is any records kept of people entering Malaysia or anything like that?
However I will definetly write to the Imperial War Museum about the documents, so thank you very much for your help!
