Hi joan,
Make sure that you have found and examined all the symbols for Winter, Spring, Summer and Autumn back at the Ager house, and read the note inside the cookbook, as well as Volume 1 of Countryside Festivals book from Celtic Corner. Then check the forest map and turn the millstones in the correct order, starting with Winter. When you return to the first millstone you should then be able to see the church.
MaG's walkthrough is
HERE if you need to double check what each symbol should look like.
