Blackburnshire

Blackburnshire was a hundred, an ancient sub-division of the county of Lancashire, in northern England. Its chief town was Blackburn, in the northwest of the hundred. It covered an area similar to modern East Lancashire, including the current districts of Ribble Valley (excluding the northern part, which was then in Yorkshire), Pendle (excluding West Craven, which was in Yorkshire), Burnley, Rossendale, Hyndburn, and Blackburn with Darwen.
