Thank you very much for all the helpful advice on where to start looking for possible answers to my "Born at Sea 1811". I was so pleased to find your reply and now at least I have some idea where to start. I will post "answers" if and when I find them, so if you are interested to know the results, please keep checking this message board. I feel it will take some time as I am in Australia and am not planning a trip to Kew I will appoint a researcher and then wait for any news from them. Thank you so much again for your wonderful help.
