Jeffreys and his wife were friends of Thomas Love Peacock, the novelist and poet, whose wedding took place at the castle in 1820.

The Jeffreys were originally from Shrewsbury and had moved to Ceredigion (then Cardiganshire) in the mid-18th century to develop lead smelting mills.

[1] In 1819 Jeffreys was made High Sheriff of Cardiganshire and the following year his close friend, Thomas Love Peacock, married Jane Griffith, an event celebrated by their reception at the castle.

[5][6] The castle was later used as an hotel,[7] a wedding venue and a bed-and-breakfast establishment[8] That usage ended in September 2019 when the property was listed for sale, described as beautifully restored by Country Life magazine.

[10] The Agrarian and Industrial revolutions of the mid-18th century saw the emergence of Gothic Revival architecture, which began to challenge the dominance of the Baroque.

Glandyfi is on a much smaller scale, but stands comparison with Stanage Park at Knighton, just over the border in Powys.
