 During the development of the South Wales coalfield and Cardiff Docks, the parish was gradually absorbed into the Borough of Cardiff during the 19th and 20th centuries.Seen as a clean and green up-market countrified village location close to the fast developing city, many of the better-off coal merchants and business people chose to live in Llandaff, including the Insole family.The house now known as Insole Court dates originally from 1856.
