Hi,  I am really hoping that somebody can help.  My deceased Grandfather told stories when we were children of his time in the Merchant Navy and how he escaped a Japanese Prisoner of War Camp!  I have almost no information to go on other than his name; James John DICKENSON.  Born 23rd March 1905 in Sculcoates, Yorkshire.  How can I even find out if he was in the Merchant Navy?  We were never allowed to talk about him to anybody and I know that he did take on somebody else's dead identity later in life!  It's all very strange.  How can I find out any information as I have no living relatives to ask.  Any help we would be so appreciated.  Fingers crossed and thank you.
