- This family was descended from Henry Cavendish, a natural son of Henry Cavendish (died 1616), elder brother of the 1st Duke of Devonshire. A descendant, Henry Cavendish, came to Ireland circa 1730 and in that year married Anne, daughter and co heiress of Henry Pyne of Waterpark, county Cork, son of Sir Richard Pyne, Lord Chief Justice of Ireland. Henry was created a baronet in 1755 and died in 1776. In 1757, his son, also named Henry Cavendish, married Sarah, only daughter and heiress of Richard Bradshaw. She was created Baroness Waterpark in 1792. Their son, Richard, succeeded as 2nd Baron. At the time of Griffith's Valuation the estate of the 3rd Baron was mainly in the parish of Tubbrid, but also in the parishes of Tullaghorton and Whitechurch, barony of Iffa and Offa West, county Tipperary. This family had an English seat at Doveridge Hall, Derby, and in the 1870s the Irish estate amounted to 3,465 acres in county Tipperary. In July 1853 land at Scartana, county Tipperary and in counties Kildare and Dublin, the estate of the Reverend Frederick Cavendish, grandson of the 2nd Baronet, was advertised for sale. Land at Scart, barony of Iffa and Offa West, belonging to Henry Coleman and held from Lord Waterpark was advertised for sale in December 1856.
