Hi,
Just re-reading your message. I know Richard Cain was my Mum's great Uncle (worked in House of Keys) and I know for sure that Stanley worked the IOM steam packet, he had a daughter who was my great grandmother May Pheobe Cain who grew up to marry a Powell, they had a number of children, Dolly, Olive, Charlie, Evelyn and Tom, Tom is my maternal grandfather. There are a few of us still around up here if you would like any more information. Have a few photo's too.
Kind regards
Helena Paxton
