- The Newport family were influential in both the commerical and political life of the city of Waterford during the later eighteenth and early nineteenth centuries. Morris states that Simon Newport, a merchant of south Tipperary, moved to Waterford in the early eighteenth century and married into the Barker family. Sadleir, referring to the 1770s, also notes "Simon Newport, banker". His grandson, Sir John Newport, of Newpark, was created a Baronet in 1789. He served as an MP for the City of Waterford. After his death his trustees offered over 1000 acres for sale in the Encumbered Estates Court in 18555 and 1856. The sale included the mansion house at Newpark.
In 1870, Charles Newport, resident in Belgium, offered for sale in the Landed Estates Court lands at Rathculiheen, barony of Kilculiheen, county Waterford. The sale notice indicates that he had purchased this property in the Encumbered Estates Court in 1857.
