:Thanks.  It's in very early, even experimental stage at present - really just collecting some info and ideas.  It's going to be big, so I'm not sure at this stage how much description there will be.  It's taking a lot of time; at present I am in the 900s of a database of nearly 3,000 (better than Pastscape with over 6,000 for Cheshire). Yes, keys are necessary; I'll probably not bother with the HER numbers but, as a reference document, I think the SM numbers should be there.  I've started including a reference to the Revealing Cheshire's Past site for the latest entries - you might like to have a peep at one of them to see the sort of info it includes.  I think it's going to take quite a time - and I'd like to add coordinates if I can find the sites with help of Earthtools.  Best of luck! Peter.
