'Wellhouse Cottages' almost certainly refers to what is now called Wellhouse Square. Built by Billycock Bracewell as tied occupation for workers at the nearby Wellhouse Mill. His Burnley interests were mainly engineering and I doubt if there would be any natural transfers of workers between the two other than the general ease of flitting in those days due to easy rail communication and the widespread availability of rented accommodation with agents to help find it. The evidence for this ease is how rapidly the town emptied when Bracewell Brothers collapsed after Billycock's death. The Craven Herald reported at the time that grass was growing on the streets. Billycock's biggest problem at that time was getting enough workers for his two mills in Barlick, he imported children from workhouses, a common ploy at that time. (See Gregg's at Styal doing exactly the same thing) I doubt if he would have encouraged anyone to leave.
One small point, '201 Wellhouse Cottages' sounds like a transcription error to me. There are approximately 40 dwellings in the Square.
