Hi,
On my 1885 map, Stanley House is marked, on the west side of Back Lane, a northerly extension of Peacock Street later incorporated in Peacock St. It says Stanley House (girls). Girls in italics. I think this suggests "wayward girls" and your matron would go someway to confirm this. By 1927 Stanley House is at 68 Peacock St., the property of George Tate, a remote relation of mine who was into cheap property purchasing, soft fruit growing and jam making ...as if you needed to know! My guess is Stanley House would have been demolished in the late 1930's as part of the slum clearances in the area. Peacock Street and the houses on ite east side survives, but the west side is now as far as I recall the backs of modern commercial properties in Magdalen St.
