CYNNULLMAWR (CYNNULL-MAWR), a township, in the parish of LLANVIHANGEL-GENEU'R-GLYN, upper division of the hundred of GENEU'R-GLYN, county of CARDIGAN, SOUTH WALES, 6.1 miles (N. E. by E.) from Aberystwith, containing 636 inhabitants. This township takes its name from an elevated mountain, at the western base of which the road from Aberystwith to Machynlleth passes: it is bounded on the north by the river Lery. Glanvraed, an old mansion on the left bank of this river, is remarkable as the supposed birthplace of the celebrated antiquary, Edward Llwyd, author of the Archaeologia Britannica, and many other works on the natural history and antiquities of Wales: he also collected a great number of ancient British records, which were afterwards unfortunately destroyed in the fire which consumed HavSd House, in this county. The township is separately assessed for the support of its poor, the average annual expenditure amounting to £ 219. 14.
