Much of Howard’s early life is difficult to disentangle from that of his cousin and namesake, Thomas Howard‡, the son of Theophilus Howard†, 2nd earl of Suffolk. Like his brothers Howard had been a royalist during the Civil War. He may have been the father of Moll Davies, a mistress of Charles II, with whom she had a daughter, Lady Mary Tudor.
The exact date of Thomas Howard’s succession to the earldom of Berkshire is unknown. His writ of summons was issued on 16 Apr. 1679, so his brother’s death must have taken place before that date. The peerage seems to have been something of an empty honour, as John Verney wrote on 17 Apr. that the death of Berkshire ‘prefers his brother Thomas Howard (of the Guards) to the title, though very little income accompanies it to support the grandeur.’
As his brother had been abroad and disabled from sitting as a Catholic, it seems plausible that the forecasts made by Thomas Osborne, earl of Danby (later duke of Leeds), about the likely voting in the proceedings against him refer to the 3rd earl of Berkshire, rather than the 2nd. Berkshire was listed as a potential supporter, with Peregrine Osborne, Viscount Dunblane [S], the future 2nd duke of Leeds, given the task of canvassing his support. He appeared on two more lists as a probable supporter, and finally his name was added to a list which may indicate that the 3rd earl voted against Danby but that Danby had not given up hope of securing his support. On 10 May 1679 Berkshire voted in favour of appointing a joint committee of both Houses to consider the method of proceeding against the impeached peers and entered his dissent to the resolution not to do so. On 27 May he probably voted for the right of the bishops to stay in the House during capital cases.
In August 1680 Berkshire wrote to Danby, referring to his obligations to that peer and assuring him that ‘it was never a principle of mine to run down any man of honour and quality upon a vulgar report without a legal trial to direct my judgment’.
In anticipation of his attendance at the 1681 Oxford Parliament Danby included Berkshire’s name in his pre-sessional forecast of peers who might vote in favour of bailing him, but on 23 Mar. Edward Osborne‡, styled Viscount Latimer, noted that Berkshire was one of Danby’s absent friends and the attendance lists confirm that Berkshire did not attend the House at all during this brief session.
Berkshire was present on the first day of the 1685 session and attended on 17 days until 18 June (being excused at the call of the House on 26 May and missing on 23 May and 4 June), 53 per cent of the total before the adjournment in July, being named to six committees. According to the attendance lists, when the House resumed, he was only present on 12 Nov. 1685, but he was named to a select committee on 18 Nov. as well which suggests that he was in the chamber. He was by now in receipt of a government pension of £300.
There is no evidence to suggest that Berkshire was involved in the events of the Revolution of 1688. He attended the Convention for the first time on 15 Feb. 1689. He was again present on 18 Feb. and on 6 Mar. when he confirmed his allegiance to the new regime by taking the oaths before being allowed leave of absence on grounds of ill health. He never attended the House again. On 21 Sept. 1689 he replied to the request of George Savile, marquess of Halifax, for an assessment of his personal estate for the 12d. in the pound levy, charging himself on £400.
