This article by Steven W. Morrison provides an overview of the significance of the 1821 Census of Cavan with particular emphasis on the town of Ballyhaise in the parish of Castleterra. This in-depth analysis of the returns for Ballyhaise will be of interest to local historians and anyone researching ancestors in the Ballyhaise area. It also acts as a useful guide to navigating this very important dataset which has survived for almost half of County Cavan from 1821.
