Question: Henry Cromwell's father began burying national figures in the abbey starting with whom?

full_context: Document 1: Burials and memorials in Westminster Abbey: Subsequently, it became one of Britain's most significant honours to be buried or commemorated here. The practice of burying national figures in the Abbey began under Oliver Cromwell with the burial of Admiral Robert Blake in 1657. The practice spread to include generals, admirals, politicians, doctors and scientists such as Isaac Newton, buried on 4 April 1727 and Charles Darwin buried 19 April 1882.
Document 2: Protestantism: Also, other human rights were advocated for by some Protestants. For example, torture was abolished in Prussia in 1740, slavery in Britain in 1834 and in the United States in 1865 (William Wilberforce, Harriet Beecher Stowe, Abraham Lincoln - against Southern Protestants). Hugo Grotius and Samuel Pufendorf were among the first thinkers who made significant contributions to international law. The Geneva Convention, an important part of humanitarian international law, was largely the work of Henry Dunant, a reformed pietist. He also founded the Red Cross.
Document 3: Elizabeth Claypole: Elizabeth Claypole ("née" Cromwell; 2 July 1629 – 6 August 1658) was the second daughter of Oliver Cromwell, Lord Protector of the Commonwealth of England, Scotland and Ireland, and his wife, Elizabeth Cromwell, and reportedly interceded with her father for royalist prisoners. After Cromwell created a peerage for her husband, John Claypole, she was known as Lady Claypole. She was buried in Westminster Abbey.
Document 4: Westminster Abbey: It suffered damage during the turbulent 1640s, when it was attacked by Puritan iconoclasts, but was again protected by its close ties to the state during the Commonwealth period. Oliver Cromwell was given an elaborate funeral there in 1658, only to be disinterred in January 1661 and posthumously hanged from a gibbet at Tyburn.
Document 5: Henry, Duke of Cornwall: Henry, Duke of Cornwall (1 January – 22 February 1511), was the first child of King Henry VIII of England and his first wife, Catherine of Aragon, and though his birth was celebrated as that of the heir apparent, he died within weeks. His death and Henry VIII's failure to produce another surviving male heir with Catherine led to succession and marriage crises that affected the relationship between the English church and Roman Catholicism, giving rise to the English Reformation.
Document 6: Henry Cromwell: Henry Cromwell (20 January 1628 – 23 March 1674) was the fourth son of Oliver Cromwell and Elizabeth Bourchier, and an important figure in the Parliamentarian regime in Ireland.
Document 7: Westminster Abbey: Subsequently, it became one of Britain's most significant honours to be buried or commemorated in the abbey. The practice of burying national figures in the abbey began under Oliver Cromwell with the burial of Admiral Robert Blake in 1657. The practice spread to include generals, admirals, politicians, doctors and scientists such as Isaac Newton, buried on 4 April 1727, and Charles Darwin, buried 26 April 1882. Another was William Wilberforce who led the movement to abolish slavery in the United Kingdom and the Plantations, buried on 3 August 1833. Wilberforce was buried in the north transept, close to his friend, the former Prime Minister, William Pitt.[citation needed]
Document 8: Isaac Newton: Newton died in his sleep in London on 20 March 1727 (OS 20 March 1726; NS 31 March 1727). His body was buried in Westminster Abbey. Voltaire may have been present at his funeral. A bachelor, he had divested much of his estate to relatives during his last years, and died intestate. His papers went to John Conduitt and Catherine Barton. After his death, Newton's hair was examined and found to contain mercury, probably resulting from his alchemical pursuits. Mercury poisoning could explain Newton's eccentricity in late life.
Document 9: Portrait of Thomas Cromwell: Portrait of Thomas Cromwell is a small oil painting by the German and Swiss artist Hans Holbein the Younger, usually dated to between 1532 and 1534, when Cromwell, an English lawyer and statesman who served as chief minister to King Henry VIII of England from 1532 to 1540, was around 48 years old. It is one of two portraits Holbein painted of him; the other is a tondo from a series of medallions of Tudor courtiers.
Document 10: Westminster Abbey: During the early 20th century it became increasingly common to bury cremated remains rather than coffins in the abbey. In 1905 the actor Sir Henry Irving was cremated and his ashes buried in Westminster Abbey, thereby becoming the first person ever to be cremated prior to interment at the abbey. The majority of interments at the Abbey are of cremated remains, but some burials still take place - Frances Challen, wife of the Rev Sebastian Charles, Canon of Westminster, was buried alongside her husband in the south choir aisle in 2014. Members of the Percy Family have a family vault, The Northumberland Vault, in St Nicholas's chapel within the abbey.
Document 11: Westminster Abbey: Henry III rebuilt the abbey in honour of a royal saint, Edward the Confessor, whose relics were placed in a shrine in the sanctuary. Henry III himself was interred nearby, as were many of the Plantagenet kings of England, their wives and other relatives. Until the death of George II of Great Britain in 1760, most kings and queens were buried in the abbey, some notable exceptions being Henry VI, Edward IV, Henry VIII and Charles I who are buried in St George's Chapel at Windsor Castle. Other exceptions include Richard III, now buried at Leicester Cathedral, and the de facto queen Lady Jane Grey, buried in the chapel of St Peter ad Vincula in the Tower of London. Most monarchs and royals who died after 1760 are buried either in St George's Chapel or at Frogmore to the east of Windsor Castle.[citation needed]
Document 12: Mary Cromwell, Countess Fauconberg: Mary Cromwell, Countess Fauconberg (9 February 1637 (christened) – 14 March 1713) was an English noblewoman, the third daughter of Oliver Cromwell and his wife Elizabeth Bourchier.
Document 13: Monarchy of the United Kingdom: The Civil War culminated in the execution of the king in 1649, the overthrow of the English monarchy, and the establishment of the Commonwealth of England. Charles I's son, Charles II, was proclaimed King of Great Britain in Scotland, but he was forced to flee abroad after he invaded England and was defeated at the Battle of Worcester. In 1653, Oliver Cromwell, the most prominent military and political leader in the nation, seized power and declared himself Lord Protector (effectively becoming a military dictator, but refusing the title of king). Cromwell ruled until his death in 1658, when he was succeeded by his son Richard. The new Lord Protector had little interest in governing; he soon resigned. The lack of clear leadership led to civil and military unrest, and for a popular desire to restore the monarchy. In 1660, the monarchy was restored and Charles II returned to Britain.
Document 14: Montevideo: The other large cemeteries are the Cementerio del Buceo, Cementerio del Cerro, and Cementerio Paso Molino. The British Cemetery Montevideo (Cementerio Británico) is another of the oldest cemeteries in Uruguay, located in the Buceo neighborhood. Many noblemen and eminent persons are buried there. The cemetery originated when the Englishman Mr. Thomas Samuel Hood purchased a plot of land in the name of the English residents in 1828. However, in 1884 the government compensated the British by moving the cemetery to Buceo to accommodate city growth. A section of the cemetery, known as British Cemetery Montevideo Soldiers and Sailors, contains the graves of quite a number of sailors of different nationalities, although the majority are of British descent. One United States Marine, Henry de Costa, is buried here.
Document 15: Lord Protector: The Lord Protector of the Commonwealth of England, Scotland and Ireland was the title of the head of state during the Commonwealth (or, to monarchists, the Interregnum), following the first period when a Council of State held executive power. The title was held by Oliver Cromwell (December 1653 -- September 1658) and subsequently his son and designated successor Richard Cromwell (September 1658 -- May 1659) during what is now known as The Protectorate.
