I guess what you are seeing is the non conformist "Circuit" aligned to an area rather than a rigorous Conformist Parish (?)

For the record the area of Lydbrook is confusing in that it lies across the East and West Dean ex parocial areas.

Lydbrook - East Dean is Horslea( Hausley or what ever !), Joys Green, The Pludds, Reddings etc

Lydbrook - West Dean is Worral Hill, Hangerberry, Camomile Green etc
