It was a small parish, in both area and population and contained no townships.
A parish church dedicated to Saint Erbin was mentioned as far back as the 13th century but the present church, dedicated to Saint Hilary, was constructed in 1860.
Wrexham historian Alfred Neobard Palmer suggested that the name derives from "Erbin's stoke" meaning Erbin's stockaded ford.
The village became important as a crossing point on the River Dee, near the 17th century red sandstone Boat Inn. The inn takes its name from the hand-operated chain ferry which once crossed the river at this point, with remnants of the pull mechanism still existing nearby.
The village and its surrounding area have been defined as the Erbistock Village and Conservation Area by Wrexham county borough council. It includes Erbistock Hall (Grade II listed), Erbistock Mill, St Hilary's Church (Grade II listed), The Boat Inn (Grade II listed), The Old Rectory and Rose Hill (Grade II listed).
