History

Gentry house, probably early C19 in origin, remodelled in 1880s. Hayston is recorded from C16 as a yeoman house: John Mabe in 1550, David Mabe in 1607. There were three properties in 1786, owned by Philipps, Mathias and Lord Kensington, all tenanted.
In 1699 and 1759 one of the properties was owned by the Jordans of Dumpledale, then sold 1759 to Rev O. Philipps of Haverfordwest. The second property was sold in 1785 by assignees of Marmaduke Gwynne to R. Mathias of Tierston, and the third was owned by W. Edwardes of Johnston, created Baron Kensington in 1776. This house is the Mathias house: Richard Mathias came to live at Hayston sometime after 1786 and probably rebuilt c. 1800. He died before 1814, when his son, also Richard was there. What was called the mansion house of Hayston, of the late Richard Mathias, was sold in 1837 with Hayston Mill. Hayston Hall was occupied by T. H. Davies in 1877-88, who may have been responsible for the remodelling. Said to have been owned by the Tasker family.
