Biographical history

Cilymaenllwyd mansion was at one time owned by the Mansells of Mudlescwm, Carmarthenshire. The mansion changed hands several times before it passed into the hands of the Howard-stepney family of Llanelly House, Carmarthenshire, early in the twentieth century and from them to the Murray-Threiplands. In 1985 Cilymaenllwyd mansion became a private nursing home.

The Stepney family was established at Prendergast, Pembrokeshire, from early in the second half of the sixteenth century until at least 1670. However, the house was in ruins by 1767, as the family had moved to Llanelli House, Carmarthenshire, rebuilt by Sir Thomas Stepney, the fifth baronet (d. 1744), and the Pembrokeshire estate was sold in 1772.

The family failed with the death of Sir Thomas Stepney (d. 1825), the ninth baronet. The family property passed to descendants on the female side who had married into the Gulston family of Derwydd, Carmarthenshire. They took the name of Stepney-Gulston, and later Cowall-Stepney. The estate eventually passed to Katherine Meriel Cowell Stepney, who married Sir E. Stafford Howard (d. 1916).
