Hi Imison
The poet was a chap called Samuel Taylor Coleridge......
His cottage in Nether Stowey was lent to him by Rev.Thomas Poole.
Rev Thomas Poole was a nephew of Rev.Edward Poole who started the first free school in England at Enmore.
I am in contact with the descendants of Rev.Thomas Poole, as I mentioned they have the family tree in great detail - I believe it was compiled by your Rev John Poole but am not 100%.
I will pm you my e.mail address - the chap I am in contact with is the guy you need to talk to, but he only has a landline number.
I am not related, I have been researching our house which was built by a solicitor, Joseph Ruscombe Poole in the 1860's and have just sort of wandered into the Poole family history!
I dont have a copy of the diary but the chap I can put you into contact with is the author!!
Regards
Pete.
