Thanks Shaun - I'll have a look at that (I haven't had any luck finding it on another map I've been examining).
Drykid, that's a nice diary on ebay. I'm afraid I couldn't sell that even if I was a dealer as this person appears to be ...

I hope Westminster can help us find out some more about where the diary has been between Nathaniel's ownership and the person they purchased it from. The people currently working there know nothing about it's acquisiton, but they were going to try to contact a previous archivist who may know more. It also makes me wonder if Nathaniel kept hold of the diaries he wrote in his youth till his death, or whether a family member had them, or someone else?

Of course there could be more of Nathaniel's diaries in lofts somewhere ...

We live in hope.

It's also worrying because still today people are throwing out this kind of precious history.
