Thank you for the feedback.
My GGF was in the Merchant Navy, but I have no idea in what capacity, he was a strange one seemed to live separate lives at home and at sea. No paperwork has been found.

Spike I will pm the names if that's ok. I realise you have stuff going on at the moment so there's no rush, you can do it in the wee small hours when your wide awKe feeding the baby .

Thanks again to all for the help.
