Rhydderch ap Hywel ap Bedo is the earliest named owner of Derwydd, in 1550. His only child, Elizabeth, also had an only child, Sage, who married Sir Henry Vaughan of Golden Grove, who came to live at Derwydd. Following Sir Henry's death, the estate was inherited by his daughter Rachel who married John Vaughan of Derllys. He was succeeded by his son Richard Vaughan of Derwydd who died without issue. The estate passed to his daughter, Elizabeth Lloyd, who married Sir Thomas Stepney of Llanelli. After the deaths of his sons without issue, the estate passed to his daughter, Elizabeth Bridgetta. She married Joseph Gulston in 1767, and the estate remained with their descendants until at least the 1980s.

The Vaughan family owned the Pontfaen estate, Pembrokeshire, since at least 1501 until the marriage in 1625 of Francis Laugharne, son of John Laugharne of St. Brydes, Pembrokeshire, and Lettice Vaughan, daughter and heiress of James Vaughan of Pontfaen. In 1750 or 1751, Anne Laugharne, daughter and heiress of William Laugharne of Pontfaen, married Rowland Philipps of Orlandon, Pembrokeshire, who then adopted the surname Philipps Laugharne. The Pontfaen and Orlandon estates then descended upon John Philipps Laugharne, John Edmund Philipps Laugharne(alive in 1816). His heir may have been Sir William Philipps Laugharne and, if so, the estates were in some financial difficulties by the mid-1820s at the latest. In 1823, the Pontfaen estate was sold to a Henry Rees of the parish of Roch, Pembrokeshire. In 1835, Sir William Laugharne Philipps conveyed in trust for sale the Orlandon estate and by 1839 it was the property of William Charles Allen Philipps.
