Hello, yes i have seen these, Calcutta seems to be quite central to everything, they left India from Calcutta in1928, the two boys the father Christopher Gilbert, and it says Mrs Dowden. But he remarried a Mary Anne Webb 8 Dec 1923 and the original Mrs Dowden also remarried 1929. Makes me wander if Alan has a different mother or father maybe, fathers love child and then wed Dorothy?? Who he had a child with, or even Dorothys previous relationship?? Bit of a hunch maybe. Could be why no reg. as yet. What do you think? By the way thanks for your reply.
