"This quiet little village, on the confines of Halkyn mountain, forms a remarkably pleasant excursion from Mold, from which it is about four miles distant. ... The highway branches off to the right, along a narrow lane that will prove attractive to the botanist, and the lover of wild flowers, for here nature displays her varied chorus, according to the season of the year, primroses, hyacinths, cowslips, wild roses, honeysuckle, ferns, foxgloves, and innumerable other wayside flowers gladden the sight, and give the air the redolence of their perfume."
[From Handy Guide to Mold and the Neighbourhood ; Tweddel, 1890]
The "London Gazette" of the 27th October 1876 defined the boundaries of the new parish thus:
All that part of the parish of Northop in the county of Flint and in the diocese of Saint Asaph which is comprised within and is co-extensive with the limits of that portion of the township of Caerfallwch wherein the present incumbent of the said parish of Northop now possesses the exclusive cure of souls, or in other words, which consists of that portion of the said township of Caerfallwch which is not included within the limits of the consolidated chapelry of Saint John, Rhydymwyn, in the county and diocese aforesaid.
The new parish of Caerfallwch was created on 23 October 1876, from part of the township of Caerfallwch, which until that time had been in the parish of Northop.
(The parish of Northop had already lost another part of the township of Caerfallwch in 1865, to the new parish of Rhydymwyn).
