Yes, we did go to England last June and did find the church. We took the train from London to the Luton Airport Station. This was important because we were advised not to get off at the Luton Station which was after the Airport Station. We easily got a cab there and between our MapQuest directions and the driver's GPS, we were in Kings Walden in about 15-20 minutes. There was a very nice lady who runs the small landscape nursery across from the church - Louise - who had a key so we were able to go in. The church records are in Hitchin, however. So if you want to go there, or spend more time exploring the area, then I suggest renting a car.
