I love old historic churches! For christmas last year my MIL got me a historic photograph book called "British Churches". It contains b/w photographs from the Francis Frith collection. According to the book there is Shere Church on the Tillingbourne, Wotton church near Dorking, St. Peter's church in Newdigate, St. Andrew's church in Farnham, St. Peter's church in Chertsey. It might be worth googling each of them. The book contains little snippets of historical events about each but that would be too much for me to type, I'm afraid!
