The best account of this person is given in his monumental inscription in Boughton-Malherbe church: "Here lies the body of Mr. Daniel O'Neale, who descended from that greate, honourable , and antient family of the O'Neales, in Ireland, to whom he added new luster by his own merit, being rewarded for his courage and loyalty in the civil warrs, under King Charles the First and Charles the Second, with the offices of Postmaster General of England, Scotland and Ireland, Master of the Powder, and Groome of His Majesty's Bedchamber. He was married to the right honourable Katherine Countess of Chesterfeild, who erected him this monument, as one of the last markes of her kindness, to show her affection longer than her weak breath would serve to express it. He died A.D. 1663, aged 60". (Warrington)

Daniell O'Neille (as he himself signed his name) was a wealthy man of good family, who was active during the Civil War in support of Charles I. He was concerned in 1641 with Digby, Wilmot, Goring, and Ashburnham, in the "Army Plot," the object of which was to support the king, uphold the church, and overawe the parliament. He was placed in the Tower, but managed to escape in woman's clothes, and a few months later he was Lieutenant-Colonel of Horse under Rupert. At Marston he led Prince Rupert's regiment of foot, and in 1658 he accompanied the Marquis of Ormonde in disguise to London, and remained there some time, holding meetings with the Royalists, and sounding them as to the prospect of a successful rising against Cromwell (see "The Pythouse Papers," ed. W. A. Day, 1879, pp. lvlvii, 25).
