‘Place-Names of Montgomeryshire’ examines 900 place-names in the historic county of Montgomery (1536-1974) together with the southernmost part of Denbighshire that was transferred to Powys from Clwyd in 1996. Place-names tell us a lot about how our ancestors lived, their languages and dialects, and how they thought about the world around them but great care must be taken to gather as much written and spoken evidence as possible before attempting to interpret those names.
