Worthenbury is situated in the northern part of Maelor Saesneg, the detached part of Flintshire. It is an extensive area of fertile farmland.
For more than 600 years, life in the village of Worthenbury was dominated by the Puleston family, who were the squires of the nearby Emral Hall.
Worthenbury was originally a parochial chapelry in the parish of Bangor Is-coed. In 1658, during the Commonwealth Period, it was designated as a parish in its own right - but in 1661, after the Restoration, this was declared invalid.
In 1689, Sir Roger Puleston obtained an Act of Parliament, and Worthenbury again became a separate parish. It was in the diocese of Lichfield until 1541, when it was transferred to the newly created diocese of Chester. In 1849, it was transferred to the diocese of St. Asaph, where it remains.
