From the Paganels, Ripley passed to the Trusbut family, how does not appear, and from them, by the marriage of the heiress, to the family of de Ros of Ingmanthorpe, a branch of the de Ros's of Hamlake and Holderness, who became the superior lords, under whom the manor was held for half a knight's fee, early in the twelfth century, by a family whose previous name is not recorded, but who adopted that of de Ripley from their possessions. From this family descended the famous Canon of Bridlington, Sir George de Ripley, in the fifteenth century, the alchymist and "discoverer" of the philosopher's stone, as he professed, in 1470, and who contributed annually vast sums of money to the Knights of Rhodes for maintaining their warfare against the Mussulmans. The Ingilbys are of Scandinavian origin, seated for a long period at Engelby, in Lincolnshire, whence they derived their surname, who, at the time of Domesday Book held three manors in Lincolnshire, two in the North Riding of Yorkshire, under the Bishop of Durham and William of Poictou, and one in Derbyshire. In 1350, or thereabouts, Sir Thomas de Ingilby, Justice of the Common Pleas, married Catherine of Luerne, daughter and heiress of Bernard (?) de Ripley, and came into possession of the Ripley estates, where he settled, and, seven years afterwards, obtained a charter for an annual fair and weekly market at Ripley. The Ingilbys, still extant, have held a distinguished place among the families of Yorkshire, and many members of the family have been entrusted with high offices in Church and State, and become eminent in the field.
