Yes, I agree, it is like looking for a needle in a haystack, thats true. However, looking at the population for the area, a list created from the 1911 census will have roughly 5000 male names. This number can be reduced still further due to events such as WW1, the spanish flu epidemic, mining and other work related deaths. Still further by marriages prior to 1920. Therefore, it should be possible to eventually get down to a completely manageable list.

Of course, with no names on the birth certificate, I'll never be able to prove things, thats something else that I will agree with. It may sound odd, but I'm not really interested in proving anything. Just simply finding out the likliest name from my past, and leaving it at that. If that name then happens to turn up on someone elses family tree, which it may, so be it. I have already decided that I will not be making contact with any of his descendents, though they would be welcome to make contact with me if they should wish.
