Is that Frank? I'm so glad you got in touch - I lost your e-mail address when my computer crashed a few yeas ago and I had to replace the hard drive.
I haven't done much more research on the Pratts - I found a William Pratt of the right age in the Stratford-upon-Avon records and traced some of his family, but I now think it's probably not him - he seems too well-to-do to be ours.
I did discover that James Pratt's mother, Ann Turner, was also from a brickmaking family near Coventry.
An old schoolfriend of mine is now vicar of Launcells, so I hope to go down and do some investigations at some point, but as I'm now caring full-time for elderly parents, it's been hard to find the time.
