Extracts from 'A Topographical Dictionary of Wales' by Samuel Lewis 1833
"HIMMINIOG (AMMINIOG), a township in the parish of LLANRHYSTID, lower division of the hundred of ILAR, county of CARDIGAN, SOUTH WALES, 9 miles (S. S. W ) from Aberystwith, containing 785 inhabitants. This township is situated on the sea-shore, on the road from Aberystwith to Aberaêron and contains the parish church : it forms the lower division of the parish. The river Gwyrai flows through it into Cardigan bay, in which, at flood-tide, here are six fathoms of water, within half a mile of the shore. The fortress called Llanrhystid or Dinerth castle, is said to have stood in this division of the parish, but there are no remains of it."
"MEVENNYDD (MEVENYDD), a township in the parish of LLANRHYSTID, lower division of the hundred of ILAR, county of CARDIGAN, SOUTH WALES, 10 1/2 miles (S.) from Aberystwith, containing 740 inhabitants. There are some respectable residences in this township, one of which is Mabus, a pleasant seat of the Lloyds, situated on an eminence above the small river Gwyre. The river Aêron has its source here, in a small lake called Llynaedwen."
