Gilbert de Southworth of Warrington acquired half of the manor by marriage to Alice d'Ewyas and is credited with building the Great Hall around 1325.

Bradyll never lived at the hall but stripped much of its interior features to use at his main house of Conishead Priory at Ulverston.

The next owner was John Cooper, who bought the building in 1850 and leased it to Mrs Mary Ann Harrison as a co-educational boarding school.

She established a Pestolozzian Institution at the hall, based on the ideas of the 18th-century Swiss educational reformer Johann Heinrich Pestalozzi.

A fall on the ice in January of that year caused traumatic injuries to William's brain and a leg, resulting in extreme depression.

Therefore, Samlesbury Hall reflects the building styles and religious beliefs from the 14th century to the present day.
