I have found HO107/222 Fol 7 Page 8 at Halberton, Devon, Parish Sampford Peverell, Address Higher Town. Head is Woodbury, Henry 60 Ag Lab, Woodbury, Mary 60, Collard, James 50 Ag Lab, Born Devon. (This fits my James.) On Fam search it give the reg district as Tiverton & Dulverton, which matches with the Slomans, who his daughter Sarah married into. The Slomans moved back and forwards between Tiverton in Devon and Milverton in Somerset. I think this is fairly promising.
