Thank you Roy for this. However, I do not believe, on the other evidence I have at present, that this family had anything but a most distant relationship with the one I have been researching. Names & dates don't math up as far as I can see, and the family whose details you have sent appear to have a very much more elevated and erudite status than mine. I have had considerable difficulty in separating out at least two Gower lines within the Pembrey Llanelli area, and one of these was much more connected with the land in the XIX c. than mine, who, at least when they could find work, found it underground.
Regards,
Mike
