The Domesday Project 1986 was made to coincide with the 900th year anniversary of the original Domesday Book. Many familiar local names occur in it. Unfortunately Domesday 1986 was done on rapidly obsolete computer technology and was nearly lost forever. It has now been put on the web
here. You will have to navigate within it to Hemyock yourself. I have taken the liberty of printing off the text about
Hemyock and about the
Blackdowns as Adobe Acrobat files for ease of access. There is a
photo taken from the top of Pencross Hill in 1986 as well.
