In the 1920s, Robert Crawley lost most of the family wealth on a investment which sadly went wrong, meaning that he and his family may have needed to sell it. However, it is possible, when Robert's heir and son-in-law Matthew recieved a large fortune, the family didn't have to sell it.
The family stays there in 1923 for the London summer season, which includes Rose MacClare's debunate ball.
