Robert Howcott and the Regicides
King Charles I was beheaded on 30 January 1648/9 on a scaffold erected outside the Banqueting House in Whitehall, London. Three days earlier, he had been condemned to death for “High Treason, and other Crimes and Misdemeanors” following a trial at Westminster Hall before a High Court of Justice set up by the House of Commons especially for the purpose. One week after the execution, the House of Commons passed a bill abolishing the Monarchy. A republic entitled the “Commonwealth of England” was proclaimed in May 1649 and remained in existence until December 1653. From then until his death in 1658, Oliver Cromwell ruled as Lord Protector. After a period of political instability, Charles - the eldest surviving son of the executed King - was invited back to rule England as Charles II.
Before returning to England in May 1660, Charles II had issued the Declaration of Breda, which set out the terms on which he proposed to rule. These included a free and general pardon of those who had rebelled against him and his father. However, an exemption was made of unidentified people who were to be chosen by Parliament. After some debate, the Indemnity and Oblivion Act became law on 29 August and pardoned previous treason against the crown, but excluded the men involved in the trial and execution of Charles I. 31 of the 59 Commissioners who had signed the King’s death warrant were still alive at that stage. Efforts had already started to apprehend these people, who are generally known as the “regicides”.
Amongst those arrested were John Downes on 18 June 1660  and Vincent Potter , both of whom had signed the death warrant. A petition by Robert Howcott, seeking the reward of an office under the Crown, describes his role in apprehending them.

The document is not dated but it appears to have been submitted to the King about July 1660.
Arresting Downes and Potter were not the only efforts Robert made to help track down the King’s enemies. On 1 August 1660, Robert Howcott appeared before the House of Lords to report "That one Talley told him, that one Tench brought Irons to the Scaffold at the Murder of the King, and dipped his Handkerchief in the Blood of the King." As a result it was ordered that Talley and Tench be summoned to appear before the House of Lords to be examined.  On 13 October 1660, at the trial of another regicide, Hugh Peters (1598-1660), Richard Nunelly testified that Peters was present at the execution and had ordered Tench, a joiner of Houndsditch, to drive staples into the block so that Charles’ head could be held in place if he should refuse to submit to the executioner. 
People and Events mentioned in the Petition
(in order of appearance, with spelling modernised)
The Petitioner’s Father
It is not certain which son of Robert Howcott (c.1575-1635) was father of the Petitioner. The grandfather had married Katherine Sacheverell at Bruntingthorpe, Leicestershire in 1600, where they had these children christened:
The only one of these offspring whose own children have been identified is Robert Howcott (alias Holcott), who married Jane Greenhill at Upton, a short distance west of Northampton, in 1631. The couple lived at Stoughton Grange, Leicestershire and had the following family christened at Stoughton parish church:
The children described as “Alive in 1655” were mentioned in their father’s will, which was written on 4 January 1655 and proved at the Court of Civil Commission on 26 February 1658.
If the Petitioner were the son of Robert Howcott of Stoughton, he would have been only about 13 years old at the time of the last siege of Pontefract Castle.
When he returned from exile, Charles II received many requests for favours from those who claimed to have supported him. It is not known whether Robert was among those whose petitions were successful.
It is feasible, but not certain, that some or all of the following Leicestershire references may be to the Petitioner:
