The only B/T breeder I know is in KY - I fear that's a little out of your range. But let me know if you want to get in touch with her and see if she knows anyone in your area. She's been breeding Cavs since the 1980's - at first strictly Blenheims then she started the B/T's in the late '90's or early 00's.
Good luck! They are beautiful. Potato chip dogs - you can't have just one!
