Good news! Mum and I decided to go to Salisbury for a mooch round the shops today so I was able to get your pictures.
I'm not sure how interment works so I don't know whether they're actually buried underneath what I found or whether there is some other arrangement, but we managed to find a really helpful Cathedral guide who was able to look them up and take us straight to them. I thought (although I don't know why) that I was looking for a plaque on the wall so I'd have never found them as the inscription stones were on the floor under rows of chairs!
Anyway, it was easy to move the chairs, so voila!
The inscription for Joseph isn't very easy to read, and his name is written as Corve, but the wording shows it's definitely our man. His wife is correctly named as Corfe and her stone is much clearer.

The organ is not the one your guys will have used, having been replaced in the late 19th century, but there is a plaque on the side which mentions Joseph and his son, Arthur.

I have taken some of the inside and outside of the cathedral, and there are also the pictures I posted above in their original size. You can view my album here...
