The rich girl-bride was his second wife, and presumably he was considerably her senior in years. His first wife was both of royal descent and alliance, being his step-father's niece, Anne daughter of the unfortunate Henry Holland, the last Duke of Exeter, found drowned between Calais and Dover in 1473,--by his wife Anne, daughter of Richard, Duke of York, and sister to Edward IV. There does not appear to have been any issue of this marriage.
By his second wife Cicely Bonville, the Marquis is said to have had the large family of fifteen (Leland makes it only fourteen) children, seven sons and eight daughters.
Of the sons, Thomas the eldest succeeded his father to the title.
Leonard, was in 1536 created Viscount Graney in the peerage of Ireland, and same year authorized to execute the office of Deputy of Ireland under Henry Fitzroy, Duke of Richmond, natural son of king Henry VIII., by Elizabeth daughter of Sir John Blount, and widow of Gilbert, Lord Talboys. In 1540 he was recalled, and the next year articles of high treason were exhibited against him, and although he had shewn the king good services formerly both in France and Ireland, was charged with a purpose to join Cardinal Pole and other the king's enemies, and to that end had left the king's ordnance in Galloway, and consented to the escape of his nephew Gerald (son of his sister Eleanor), and being brought to trial confessed all. He was thereupon beheaded on Tower Hill, and attainted by the Parliament then sitting.
This nephew, he had consented to the escape of, was Gerald, his sister's eldest son, who subsequently became the eleventh Earl of Kildare. He was born in 1525, and at the time of his half-brother's execution about ten years of age. Henry VIII., "being very averse to his whole family, and offering large sums of money for his apprehension," the poor youth's peril was imminent, and his escapes almost marvellous, from the treachery that environed him, and plots laid to get possession of his person; besides disease and accidents of extraordinary nature that otherwise threatened his existence. But he contrived to keep safe until after the death of Henry VIII., when Edward VI. reinstated him in much of his forfeited property, and Queen Mary, at the intercession of Cardinal Pole, restored him, 13 May, 1554, to the titles of Baron Offaley and Earl of Kildare.
