Administrative/Biographical history: The Thomas family were granted a lease of Cilciffeth, Pembrokeshire, in 1700. William Thomas, solicitor, resided at Cilciffeth in the mid 18th century. Elizabeth, youngest daughter of John Thomas (d. 1750), of Cilciffeth married Griffith Gwynne (d. 1796) of Court in the parish of Llanllawer, Pembrokeshire, who appears to have acquired Cilciffeth. Court itself was sold in 1799 by Thomas and Anne Williams of Pope Hill to John Gwynne of Haverfordwest. In 1874 and 1875, the last of the Gwynnes, Anne and Martha, died unmarried and the estate passed to the Rev. Thomas Gwynne Mortimer, whose mother was a Gwynne. The Mortimer family had also acquired Penysgwarn, Llanwnda, Pembrokeshire, when John Morgan Mortimer (1798-1869) purchased it sometime after 1814. He married Lettice (1800-1871), youngest daughter of Thomas Gwynne, of Cilciffeth. By 1849, he was forced to grant Penysgwarn to trustees to provide funds for the payment of debts. The Mortimers left Penysgwarn and in 1894 one Edward Perkins held the property.
