Hi, I can tell you one place where there is wonderful information on the church and that is in Alford. My mom visted there about 1982 and brought home a wonderful history of the church. I don't have it with me because I am not at home but I believe that it was a Norman Church first. It then changed over the centuries. It also tells about some changes made in the late 1800s when it was updated. Something was added to the top which made it a little taller. They preserve as much as possible of the interior architecture and wonderful wooden pieces as possible. There were great pictures in the booklet that showed these things. It might be a good idea to make a list of places which have this great information. Velma
