Roebuck became established as a location shortly after the Norman invasion of Ireland (from 1169). In 1261, it was owned by Fromund Le Brun, the Lord Chancellor of Ireland, and a castle was built there in the 13th century, which was badly damaged in the Irish Rebellion of 1641. It was pictured in a ruinous condition by Gabriel Beranger around 1768. It was sold by Nicholas Barnewall, 14th Baron Trimlestown, to James Crofton, an official of the Irish Treasury, in around 1800.
In 1466, Elizabeth le Brun, the last of Fromund's family, married Robert Barnewall, 1st Baron of Trimlestown. The Irish Civil Survey of 1654-56 recorded that the estate consisted of around 500 acres. It remained in the hands of the Trimlestown family until the early nineteenth century when parts were sold off. The surgeon Solomon Richards acquired land in the area of the estate known as Roebuck Grove from Baron Trimlestown in 1812.
