"A parish in the Union of Llanrwst, chiefly in the hundred of Isdulas, county of Denbigh, but comprising also the township of Maenan in the hundred of Llechwedd Isaf, county of Carnarvon. ..... Its length from north to south is seven miles, and its breadth, in a transverse direction, four: the surface is very hilly, which circumstance causes a great variety of soil, some being extremely barren, and some, on the contrary, tolerably fertile, yielding good crops of corn. The village is situated in a pleasing and fertile vale watered by the river Conway, and the vicinity abounds with agreeable and richly varied scenery."
[ A Topographical Dictionary of Wales, 1833 & 1849, Samuel Lewis]
The parish of Eglwysbach comprises the townships of Maenan (in Caernarfonshire); and Esgair Ebrill, Pennant, Cefn y Coed and Bodnod, in Denbighshire.
