Hi
Just read your message.
There was a STEVENS family living in Curry Mallet (some 10 miles SE of Taunton) in the 1840's to 1860's. The father John STEVENS was a blacksmith, as was one of his many sons Simeon, who married an ancestor of mine and became the blacksmith at Butleigh, Somerset.
Hope this might help in your search.
