The Trawsgoed Estate ( Welsh for "Crosswood") is an estate located eight miles (13 km) east of Aberystwyth in Ceredigion, Wales, that has been in the possession of the Vaughan family since 1200. The family are descended from Collwyn ap Tangno, founder of the fifth noble tribe of North Wales, Lord of Eifionydd, Ardudwy, and part of Llŷn, who had his residence on the site of Harlech Castle. The land falls within the ancient parish of Llanafan, in the upper division of the hundred of Ilar. In Wales, an ancient parish was a village or group of villages or hamlets and the adjacent lands. Originally they held ecclesiastical functions, but from the sixteenth century they also acquired civil roles. The parish may have been established as an ecclesiastical parish. Originally a medieval administrative unit, after 1597 ecclesiastical units were separated from civil parishes to serve the ecclesiastical needs of the local community. The Trawsgoed estate extended over 22 Cardiganshire parishes, including Llanafan.
