Question: Coppull is a village and civil parish in Lancashire, England, it is bounded by which river, in Lancashire, with its source at an area called "Will Narr" at "Hordern Stoops", along Spitlers Edge - the Chorley/Blackburn boundary - on the West Pennine Moors?
Sentence (from "River Yarrow (Lancashire)"): Currently, this area is within the boundaries of Heath Charnock and Limbrick, but the original name was given because it was a route frequented by coal miners, and the workers were said to look like natives of Abyssinia (modern day Ethiopia): until the mid 20th century it was usual for miners to return from work covered in coal dust.
Relevant evidence: No
