Berkshire
The origin and history of Berkshire.
Etymology
From Middle English Barrokschire, Berchesire, Barrokshyre, Berrucsire, from Old English Bearrocsċīr. The first element is possibly from Proto-Brythonic *barrọg, perhaps meaning “hilly” (compare *barros (“hill, peak, top”)) + Old English sċīr (“shire, county”).
