Thanks for the response - - - never heard of Reddit and the idea of aproaching the Land Regisitry doesn't appeal. Going knocking might be an option if I lived somewhat closer than 120 miles !
I think that I've re-assured myself that the reason for my question is no longer imperative. I received an e-mail perporting to be from eBay detailing an order which I hadn't placed and the delivery address is 40 Magdalen St. - (with which I have no connection) I wouldn't normally take much notice of such potential scams but last month there was an attempt (failed) to set up a new contract with my internet hosting and the location of that hacker was reported as 'Norwich area'.
I have confirmed that no funds have been apropriated
