Fonds GB 0210 MILBORNE - Milborne Family Papers and Documents,

Blanch, daughter and coheir of Simon Milbourne of Tillington, Herefordshire, and widow of James Whitney of Whitney, Herefordshire, married, secondly, Sir William Herbert (d. 1524) of Troy Parva, knight, the bastard son of William, first earl of Pembroke. His eldest son Sir Charles Herbert directed in his will (dated 23 April 1552) that his manors of Wonastow and St Maughans be sold to pay his debts, and it is probable that Wonastow was then bought by his younger brother, Sir Thomas Herbert (d. 1588). He was succeeded by his son Henry Herbert (d. 1596). In 1603 William and Lewis, his two sons, were dead without issue, and it appears that his estate was inherited by Christian (d. 1634), one of his four daughters, who had married George Milborne (d. 1637) of Milborne Port, Somerset.

John Milborne their eldest son, was succeeded by Charles Milborne, who may have been his son. Charles was succeeded by his son George Milborne (b. 1698), who, following his marriage in 1727 to Mary Gunter, acquired the Priory estate, Abergavenny. Their son, Charles Milborne (c.1736-1775) of Wonastow and the Priory, married Lady Martha, daughter of Edward Harley, third earl of Oxford by Martha, daughter of John Morgan of Tredegar. Charles Milborne was succeeded by Mary (d. 1795), his only child, who married Thomas Swinnerton (fl. 1793-95) of Butterton, Staffordshire, esq. She was succeeded by three daughters and coheirs, Martha (dsp.) the wife of William Bagot; Mary, wife of Sir William Pilkington of Chevet, Yorkshire, eighth baronet, who appears to have inherited the estate; and Elizabeth, wife of Charles John Kemeys-Tynte of Cefnmabli, Glamorgan, and of Halswell, Somerset, esq.

Mary's eldest son Sir Thomas Edward Pilkington, 9th baronet, died without issue, as did his brother Sir William Pilkington, 10th baronet. They were succeeded by their brother Sir Lionel Pilkington of Chevet and Wonastow, 11th baronet, who in 1856 assumed the surname Milborne-Swinnerton-Pilkington. Sir Thomas, 12th baronet, the depositor of the Milborne papers, was Sir Lionel's son and heir.
