Here is part of the 1903 map "Matlock, Matlock Bath, and Borders", a large scale Ordnance Survey map published as the frontispiece in Benjamin Bryan's "Matlock Manor and Parish". The map was prepared by Stanford's Geographical Establishment, London.

This map was originally scanned for a friend interested in Riber but has now been rescanned and the overall area covered slightly enlarged to include both Hearthstone and Starkholmes.
