The third John Parker, later known as Earl of Morley inherited the house just 20 years after his father and took longer again to make any major changes to the house. However, in 1819 he employed the Regency architect John Foulston to add the Entrance Porch and create the present Library out of two smaller rooms. His second wife, Frances, continued to develop the artistic legacy of the family by producing her own watercolours and Old Master copies which are on show in the house still. The Earl of Morley was ambitious and attempted to develop several industrial and engineering projects on the estate, but many of these were unsuccessful and the family fell heavily into debt.
