Ynysclydach was built in approximately 1740 and for many years was owned by the Jeffreys family, who had owned land in the area since the reign of Elizabeth I.
In 1764, Morgan Jeffreys married Sarah Powell and three of their nine children were born at Ynysclydach.
From 1770 to the early 1800s, Rees Jeffreys who was a cousin to Morgan lived at Ynysclydach with his wife Sarah. They erected the barn opposite the main house in 1821, evidenced by an inscription stone which is still visible today.
David, who was the eldest son of Rees and Sarah married Mary Powell and between them they ran the Camden Arms, which was a coaching inn in Trecastle. Their second son Thomas died unmarried at Ynysclydach in 1843 aged 61.
The 1891 Census shows the inhabitants of Ynysclydach to be Rees Powell who was a farmer of some means and justice of the peace, his wife Mary Jeffreys Powell, and their family (seven in total) along with eight servants, a governess, cook, nurse, housemaid, dairy maid, cowman, waggoner and errand boy. Two of Rees and Mary's children, Thomas and Maud, lived at Ynys Clydach until Maud's death in 1967. The picture on the right is of Mrs Powell and her two daughters Maud and Margaret.
