Hello Fiona, I have done some research and have found that the Roger Christian you speak of says in an archive 2 message that he is " located in the iron mining region of of the upper Peninsula of Michigan,USA. Where my Grandfather Stephen Arthur settled in 1904".Two messages from Roger Christian dated 26-10-2007 and 25-10-2007. I had contacted a Roger Christian here in the IOM as I thought the message was for him but he does not follow the message board. However he has information on your line.If you want to contact him his email address is in the Isle of Man fhs journal on the inside front page under STRAYS. best wishes Pauline Johns.
