parishes Here's my rough map of the parishes of the area, as they were in the 19th Century, before re-organisation took place. The Dyfi forms a natural parish boundary over its lower reaches, but nearer its source the river is a less significant feature, and the parishes of Mallwyd and Llanymawddwy both straddle it. At some stage, Dylife became a parish in its own right, but I'm still trying to work this out.
