The history of Simonsbath and the sawmill starts with the Royal Forest of Exmoor and continues with the Knight's Estate, the Fortescue Estate and on to the present day and the ownership of the Exmoor National Park Authority.

The Estate Carpenters were the key people who operated the sawmill, acting not just as skilled woodworkers but also carrying out a range of estate management tasks.  The lives of some of these carpenters have been researched as shown here.
