|
| The map from which this extract is taken was published as part of Rammell's Report on the condition of public health in Aberdare in 1853. Heol-y-Felin (Trecynon) is one of the major centres of settlement in the Parish at that date. Settlement is also concentrated in Aberdare Village and in the vicinity of the three Ironworks at Hirwaun, Llwydcoed and Abernant. | |
