Mountjoy Blount was the eldest offspring of the celebrated (and scandalous) love match between Elizabethan courtiers Penelope, Lady Rich (traditionally believed to be the ‘Stella’ of Astrophel and Stella by Philip Sidney‡) and Charles Blount, earl of Devonshire. As such, Mountjoy was endowed with a colourful personal history, wealth, and an extensive and complex web of kinship and social connections. He was said to have succeeded to estates worth between £3,000 and £4,000 a year.
Newport took his seat in the Convention on 14 May 1660, some three weeks into the session. Eight days later he was amongst those peers given leave to attend the king. On 10 July his previous experience was acknowledged when he was added to a committee concerning deeds belonging to peers which had been in the hands of the trustees for ministers. His main activity in the House after the Restoration related to metropolitan local government. On 10 Nov. 1660 he was named to the committee for repairing highways in Westminster, and on 22 Dec. to the bill to make Covent Garden parochial.
Newport’s importance as a courtier was evident on 22 Apr. 1661 when he carried the mantle in the king’s procession from the Tower to the Banqueting House.
Newport attended the February 1663 session on its first day; he was named to the committee for privileges and to 14 other committees. It seems likely that he was present on 27 Mar. 1663 at a meeting of the committee on London streets, highways and the poor, which decided that the 21 commissioners appointed under the Paving Act were too few for the efficient conduct of local government. Newport chaired a subsequent meeting of the select committee on 12 May 1663. When the committee reconvened, Newport proposed a supplementary Act on highways, paving and sewers. Further debate in committee took place on 20 June 1663 and the commissioners, with an eye to law and order, agreed that the justices of the peace should be joined to the commission. A further meeting on 26 June 1663, again chaired by Newport, discussed the deployment of finance raised under the original Act, and inserted an urban planning clause in the proposed new legislation to prevent ‘multitudes of new buildings’.
Back in the House on 10 July 1663, Newport was present when George Digby, 2nd earl of Bristol, attempted to impeach Edward Hyde, earl of Clarendon. Newport was listed as a likely supporter of Bristol. In the brief session from March to May 1664, Newport attended on almost a daily basis. This pattern was repeated at the following session when he was named to seven more committees.
Newport was now an important figure representing the interests of the capital within the House and at court. A meeting of the mayor of London and justices of London, Middlesex, Kent and Surrey passed an order asking Newport and William Craven, Baron Craven, to petition the king that ships carrying coal should not dock for any purpose other than to supply the ports and the City.
Newport’s will reveals that his daughters Anne (married to Thomas Porter, 4th son of Endymion Porter, groom of the bedchamber) and Isabella (married to Nicholas Knollys, self-styled 3rd earl of Banbury) had already died, leaving him with three ‘incapable’ sons, each needing special care and financial provision. For this purpose, he had entered into a tripartite agreement with John Ashburnham†, William Legge† and Sir George Savile, (later earl of Halifax) to sell lands in Fotheringhay, with £2,000 of the proceeds to be invested for the care of his sons. Edward Montagu, 2nd earl of Manchester, and Charles Rich, 4th earl of Warwick, were named trustees of the interests of his granddaughter, Lady Ann Knollys.
The widowed countess of Newport subsequently married Thomas Weston, 4th earl of Portland. Newport’s three sons succeeded in turn as the 2nd, 3rd and 4th earls but each died childless and the title became extinct at the death of Newport’s youngest son, Henry, in 1681.
