No I have not had any responses at all. I have not been able to find anything at all, searching in a variety of places.
My ancestor seems to be much like yours.. not sure it was a shipwreck either, suspect he was in the Royal Navy, but not sure of that either. And with a last name of Jones, it is not easy narrowing it down.
Thanks for your reply. If you come across any decent sites, or links, etc. please let me know and I will do the same...Good luck
