On Henry Nevill II’s death at the ripe old age of 85 on 28 June 1728, the terms of his will were duly carried out. In it he arranged that ‘his youngest daughter, the Lady Mary Countess Migliorucci, should have the custody and management of his said son during his insanity, not doubting but she will see him taken all imaginable care of and used with that tenderness and regard that is due to be had for one in his unfortunate circumstance’. Then he left to his grandson, Cosmas Henry Joseph Count Migliorucci (whom he desired to take the surname of Nevill) the sum of £5,000. Next, he left to his eldest daughter, Margaret Conyers, the sum of £2,000 and to his Conyers grand-daughters, Harriet and Elizabeth, £300 apiece. To his youngest daughter, the Countess Mary Migliorucci, he left £10,000 in trust. On her father’s death, Lady Mary Migliorucci faced several problems. The first was to carry out her father’s instruction to take care of her idiot brother and for this she was allowed £200. It would seem, however, that his care fell mainly on the shoulders of Henry Milton, the bailiff of Nevill Holt, for Lady Mary spent most summers at her London house in Queen’s Square, near Ormond Street, Thus, on 3 June 1729, Milton wrote to her that ‘Mr. N. is in good health’.
