I want to know the answer to the following question:
When was the administrative county of Lancashire created?
All the background I'm provided with is that "The area served by the Lord-Lieutenant (termed now a ceremonial county) covered the entirety of the administrative county and the county boroughs, and was expanded whenever boroughs annexed areas in neighbouring counties such as Wythenshawe in Manchester south of the River Mersey and historically in Cheshire, and southern Warrington.". Is that enough to answer the question?
