Coxhoe and Cornforth are two villages next to each other. Cornforth was in the Bishop M area and Coxhoe used Kelloe, however in my family they went back and forth for what ever reason, didn't matter where they lived between the two places.
Just book a reader at the record office, don't worry about table space. You need a reader-- tell them you want it all day. There's a cafeteria for lunch.
