The parish, which was noted on a map of 1583, is in the north-west portion of the hundred of Dungleddy which George Owen in 1602 placed south of the Pembrokeshire language frontier. However, as part of the church lands to the north of the Afon Syfynwy, Owen said it was bilingual, and in modern times it has been predominantly Welsh-speaking. The percentage of Welsh language speakers was 97 (1891): 85 (1931): 50 (1971).
The parish had an area of 970 Ha.
