RCAHMW/1976, 55: ``a small holy-well' near `Bryn Cefneithan' (more correctly Bryncynneithwen, formerly a farm N. of Blaenavon in Cwm Gwenffrwd, which lies 3 miles E. of Neath).
 The site of Bryncyneithwen as shown and named on the Tithe Award for Baglan parish, 1841 (`Bryncanaithwen' in the schedule and `Bryncaenithwen' on the MS. O.S. map of 1813), is that occupied by Abergwenffrwd Row. The site of the holy well cannot be identified from several springs in the vicinity but Cae Cwmffynnon is named to the S.E. of the farm site (at SS 8045 9696)'.
