Tony, Happy to hear from you! We have some CANHAMs right over the border into Suffolk from the little town of Catfield. Can't say as I've heard about Theberton, though. I can send the file for you to look over if you have any desire. Would love to take a look at yours, also. Try making a posting to our [email protected] and maybe others can more easily see a connection with your line. Digest form of subscribing is easiest. Let me know if you need any help with that, and if you wish to see the file. Holly
