Their eldest son Robert Surtees (1694-1785) was the owner of Redworth Hall for forty years.

[3] In the same year as his marriage Robert made substantial alterations and additions to the Hall and added a rear wing.

Suddenly in 1803 he died when he was returning on his horse, in a drunken state from a banquet with Lord Barnard in Raby Castle.

Henry Edward Surtees (1819-1895) added the Jacobean style spiral stone staircase and galleried Baronial Hall in the early 1890s.

The 1881 Census shows him living at Redworth Hall with his second wife Mary Isabella who is 30 years his junior, three of his younger children, a governess, a ladies maid, a butler, a footman, a nurse and three house servants.

Folklore has it that Lord Surtees had his mentally ill child chained to the fireplace whose cries of anguish can still be heard.

It also tells the story of the peer's affair with his scullery maid, who committed suicide by throwing herself down the staircase when his wife discovered she was pregnant.
