Brynhenllan was in the ancient parish of Dinas in the hundred of Cemais before the settlement of Dinas Cross developed along the main A487 trunk road. As its name means "Old church hill", it was probably, according to Samuel Lewis and other sources, the original site of the parish church, superseded by the church of St Brynach at Cwm-yr-Eglwys to the northeast.
