Many thanks for all that. I have previously tried rootsireland and think it is probably my best bet but it is a bit of a shot in the dark to link people up. However I am going to give it another try in case I have missed something. Thanks for the help and encouragement. You wouldn't by any chance know of a site that gives information on occupations and where they were located. My Davisons were nailers so connected with the iron industry and a hint along those lines might be helpful.
