The manor was originally built by Joseph Leech, a fascinating man who was owner of the Bristol Times. Among other fun things, he used to be the "Bristol Church-goer", publishing an anonymous and apparently quite funny column as a "mystery shopper"-style reviewer of church services.
There's a bit more about him on my blog, prompted by my buying a lovely old book by him in a secondhand shop on a previous wander.
