Thanks very much for all these comments!

I tried some of the newspapers in the iMuseum a little while ago, but I think they were still in the process of digitising these resources and so only certain papers were available at the time. I will try and check out the others next time I'm on the island. I've browsed the censuses and bmds too, but had yet to find anything conclusive, so this information is a big help to me and certainly gives me some new leads.

Thanks again and all the best! Natalie
