"A tale of insects" -- Brisley's name is reckoned to be derived from the Old English for a glade or clearing with a multitude of gadflies. Something which only a scholar of Old English would be likely to know... in the main, as we're aware: if a settlement's name (unlike Brisley) looks as though it's to do with anything in "the brute creation"; it probably in fact isn't. For instance, re Buxworth, Derbyshire (near Whaley Bridge) -- formerly Bugsworth -- in the early 20th century some residents of the village seem to have been unaware of this tendency; they came to dislike the name, imagining associations with noxious insects. In fact, the name was from the Old English "Bucga's Worth" -- enclosure of the chieftain Bucga. We learn that the anti-"Bugsworth" movement was championed by the local vicar and the village school headmaster -- the village was officially renamed "Buxworth" w.e.f. 16 / 4 / 1930. (Local folk, however, still generally refer to it as "Buggy".)
