Is there a implied difference between a manor and a hall, in the case of a Georgian country house?

Answer 1

The "manor" is the house itself. Usually the "hall" will be the grand entry (foyer) or one of the larger rooms used for entertaining (such as a ballroom). That said, I have seen the two words interchanged when people are referrring to an estate such as "Smith Manor" or "Smith Hall."

Answer 2

One is the house, or manor, and one is the hall inside it. (joke)

My source calls a manor a 'big house (villa, hall or manor)' on a lot of land with outbuildings. Is that Georgian?
Georgian confused the darn source!
