Given the question: What is the last name of the person whose children, upon his death, divided the house into three separate living areas?  Answer the above question based on the context below:  The wolf head crest also appears in the late 16th-century stained glass of the Withdrawing Room. The chimneypiece in this room is decorated with female caryatids and bears the arms of Elizabeth I; its plaster would originally have been painted and gilded, and traces of this still remain.William Moreton III used what is today known as the Exhibition Room as a bedroom in the mid-17th century; it is entered through a doorway from the adjoining Withdrawing Room. Following William's death in 1654 his children Ann, Jane and Philip divided the house into three separate living areas. Ann, whose accommodation was in the Prayer Room above, then used the Exhibition Room as a kitchen. The adjoining Chapel, begun in 1508, is accessible by a doorway from the courtyard. The Chapel contains Renaissance-style tempera painting, thought to date from the late 16th century. Subjects include passages from the Bible. The chancel was probably a later addition dating from the mid-16th century. It is separated from the nave by an oak screen and projects eastwards from the main plan of the house, with a much higher ceiling. The stained glass in the east wall of the chancel is a 20th-century addition installed by Charles Abraham, the last private owner of Little Moreton Hall, as a parting gift on his transfer of ownership to the National Trust.The Corn Store adjacent to the Chapel may originally have been used as accommodation for a gatekeeper or steward. By the late 17th century it had been converted into a grain store by raising the floor to protect its contents from damp. Five oak-framed bins inside may have held barley for the Brew-house, which is now used as a toilet block.
The answer is:
Moreton
