Llanishen House, now fallen to decay, was, for more than the last two centuries, the seat of the family of Lewis : it formerly belonged to the Vaughans, the heiress of which family was married to a younger son of the Lewises of the Vann, ancestors of the Earl of Plymouth. New House, the property of John Lewis, Esq., of the same family, is a handsome modern seat, pleasantly situated at the southern foot of a lofty ridge of hills running in a direction from east to west in this part of the county.
The living is a perpetual curacy, in the archdeaconry and diocese of Llandaf, endowed with £200 private benefaction, and £ 800 royal bounty, and in the patronage of the Earl of Plymouth and C. K. Kemeys Tynte Esq., alternately. The church, dedicated to St. Isan, is a neat structure, in the English style of architecture, There is a place of worship for Wesleyan Methodists.

According to Leland, Richard William, otherwise Cromwell, afterwards Earl of Essex, who was beheaded by order of Henry VIII., was born at the mansion of New House ; but this circumstance is doubtful.
