A prominent member of the family was Charles Stewart Rolls, who co-founded the Rolls-Royce car manufacturing company.
The family's arms were described in 1852 as:[1] Quarterly: 1st and 4th, or, on a fesse, dancettée, with plain cotises between three billets, sa., each charged with a lion, rampant, of the field, as many bezants; 2nd, gu., an eagle, displayed, barry of six, erminois and az.
The first of three expansions by the Rolls family began with the architect George Vaughan Maddox who rebuilt parts of the south wing in 1830.
John Allan Rolls (19 February 1837 – 24 September 1912), sheriff in 1875 and MP for Monmouthshire, 1880–1885, created Baron Llangattock of the Hendre, 1892.
John Allan Rolls's ennoblement brought the family, and the house, to its social apogee, culminating in a visit from the Duke and Duchess of York (later King George V and Queen Mary), who stayed with Lord and Lady Llangattock at the Hendre in late October – early November 1900.
With his younger brother, Henry Alan, having died four months previously, and none of Lord Llangattock's three sons having had children, the direct male line ended.
Upon the extinction of the Rolls branch, the estate came down to his son, John Charles Etherington Harding (born 1898, Xiamen), the first cousin once removed of the 2nd Baron Llangattock, who inherited the house, estate and surrounding farmland, changing his family name to Harding-Rolls for this purpose.
The Harding-Rolls branch of the family continued to live at The Hendre until 30 August 1984 when, following a failed time-share operation, it was sold to Effold Properties Limited.
