Hi again, Sandy,
Nice to hear from you again, and thanks for those remarks!
We had our 39th Cambridge Beer Festival here in late May, and I always make a bee-line for the man with the stall who sells books that deal with Brewers. This time I picked up a copy of the second edition of "Brewed in Northants" by Mike Brown, and pages 196-200 have lots of lovely detail about DULLEY's.
By the by, there was also a good pictorial history (which I couldn't help buying as well) of the WETHERED brewing family by a former employer, David Evans, which came out only last year, 2011. My great-grandmother married into this WETHERED family in 1897...
very best wishes, keith
