Tom, if you look at the link I gave for this family you will see the chart written by Tom Brew of Canada which has the same marriage as the one supplied by Peter, and who would be your relatives if you have the same ancestors.
Please look at: http://brew.clients.ch/Douglas.htm where you will see Tom Brew's contact details.
Peter, what was the set of fiche which you bought in the IOM copied from?
Sue
