"A parish in the Union of Wrexham, partly in the hundred of Bromfield, county of Denbigh, and partly in that of Mold, county of Flint. ..... The parish is very extensive, comprising upwards of twelve thousand acres; and the village is delightfully situated on the western side of the road from Wrexham to Chester, near the head of a beautiful valley, which opens into the Vale Royal of Cheshire. ..... The little vale of Gresford is one of the most lovely in the principality, enlivened by the meanderings of the river Alyn through its meadows, and finely varied with richly wooded eminences, on one of which stands conspicuously its beautiful church, remarkable for the elegance of its architecture and its picturesque appearance." [A Topographical Dictionary of Wales, 1833 & 1849, Samuel Lewis]
Until the early nineteenth century, the parish of Gresford was of very great extent, as it included the chapelries of Holt and Isycoed, and the detached township of Erddig.
On 30 June 1840, the townships of Allington, Burton, Marford and Hoseley (a total of 6780 acres) became the new parish of Rossett.
In November 1851, the township of Gwersyllt went to the new parish of Gwersyllt.
When Archdeacon Thomas wrote his "History of the Diocese of St. Asaph" (1908 - 1913), the parish of Gresford consisted of the townships of Gresford, Llay, Borras Riffri, Borras Hofa, and portions of Burton, Allington and Marford & Hoseley.
