Question: Sir Thomas Kyriell was executed after which battle from the Wars of the Roses?
Context: Sir James Harrington, KB, MP of Hornby (? 1430 – 22 August 1485) was a prominent supporter of the House of York in Northern England during the Wars of the Roses, having been retained by Richard Neville, 5th Earl of Salisbury, who was brother-in-law to the head of the House of York, Richard of York.  He was second son of Sir Thomas Harrington, who had died with the king's father at the Battle of Wakefield in December 1460.  James himself had fought with Salisbury at the Battle of Blore Heath in 1459, where he had been captured and imprisoned by the Lancastrians until the next year.  He was a significant regional figure during the reign of King Edward IV, although the early years of the new king's reign were mared by a bitter feud between him and the Stanley family over a castle in Lancashire.  On the accession of King Richard III in 1485, he was appointed to the new king's Household, and as such was almost certainly with him at Battle of Bosworth two years later.  It is likely that he fell in battle there, although precise details of his death are now unknown. John Harrington (died 30 December 1460) of Hornby, Lancashire was a member of the English northern gentry.  He was the eldest son of Sir Thomas Harrington, a retainer of the Yorkist earl of Salisbury.  His father played an active role in the northern politics of the Wars of the Roses.  On 30 December 1460 both Thomas and his father were in the army of Richard, Duke of York at the battle of Wakefield.  The Yorkist army went down to a crushing defeat, and John Harrington was killed in battle alongside his father. Dorothy Kitson (1531 – 1577) later, Dorothy, Lady Pakington, was the daughter of Sir Thomas Kitson, a wealthy London merchant and the builder of Hengrave Hall in Suffolk.  Her first husband was Sir Thomas Pakington, by whom she was the mother of Queen Elizabeth I's favourite, Sir John "Lusty" Pakington.  After Sir Thomas Pakington's death she married Thomas Tasburgh.  She was one of the few women in Tudor England to nominate burgesses to Parliament and to make her last will while her husband, Thomas Tasburgh, was still living.  Her three nieces are referred to in the poems of Edmund Spenser. Sir Thomas Neville, (c. 1429–1460) was the second son of Richard Neville, 5th Earl of Salisbury, a major magnate in the north of England during the fifteenth-century Wars of the Roses, and a younger brother to the more famous Richard Neville, Earl of Warwick, known as the 'Kingmaker.'  Thomas worked closely with them both in administering the region for the Crown, and became a significant player in the turbulent regional politics of Northern England in the early 1450s.  His wedding in August 1453 marked the beginning of his family's armed feud with their rivals, the House of Percy, in which Thomas and his brother John led a series of raids, ambushes and skirmishe across Yorkshire against the Percys.  Many historians describe the feud as the beginning of the Wars of the Roses, a series of dynastic struggles in mid-fifteenth century England, and Thomas Neville played a large role in his father's alliance with Thomas's uncle, Richard, 3rd Duke of York. The Stepney Baronetcy, of Prendergast in the County of Pembroke, was a title in the Baronetage of England.  It was created on 24 November 1621 for John Stepney.  His son, Sir John, the third Baronet represented Pembroke and Haverfordwest in Parliament.  The latter's nephew, the fourth Baronet, married Justina, daughter of Sir Anthony van Dyck.  Their only son, Sir Thomas, the fifth Baronet, sat as Member of Parliament for Carmarthenshire.  Sir Thomas's great-grandson, Sir John, the eighth Baronet, represented Monmouth in Parliament and served as Envoy to Dresden and Berlin.  The eighth Baronet never married and was succeeded by his younger brother, Sir Thomas, the ninth Baronet, on whose death in 1825 the baronetcy became extinct. Sir Thomas Kyriell (1396–1461) was an English soldier of the Hundred Years' War and the opening of the Wars of the Roses.  He was executed after the Second Battle of St Albans. Sir Thomas Boyd of Kilmarnock was a 14th-century Scottish landowner and lord of Kilmarnock in Ayrshire.  He was the son of Sir Robert Boyd, who fought at the Battle of Bannockburn.  In 1346, he was taken prisoner at the battle of Neville's Cross.  He is known for building the earliest parts of Dean Castle in around 1350, and the castle still stands today and is open to the public.  Sir Thomas was succeeded by his son, Thomas (died 1432).  Sir Thomas' later descendants were the Earls of Kilmarnock. HMS "Sir Thomas Picton" was a First World War Royal Navy "Lord Clive"-class monitor .  "Sir Thomas Picton" was the only Royal Navy ship ever named for Sir Thomas Picton, a British general of the Peninsula War who was killed at the Battle of Waterloo.  The ship's original 12" main battery was stripped from the obsolete "Majestic"-class battleship HMS "Mars" . The Second Battle of St Albans was a battle of the English Wars of the Roses, fought on 17 February 1461, at St Albans.  The army of the Yorkist faction under the Earl of Warwick attempted to bar the road to London north of the town.  The rival Lancastrian army used a wide outflanking manoeuvre to take Warwick by surprise, cut him off from London, and drive his army from the field.  The victors also released the feeble King Henry VI, who had been Warwick's prisoner, from his captivity.  However, they ultimately failed to take advantage of their victory. The Royal Navy employed two vessels designated as His Majesty's Hired armed vessel "Sir Thomas Pasley" during the French Revolutionary Wars.  The two vessels were named for Admiral Sir Thomas Pasley.  The vessels are also sometimes described as cutters, but more generally as brigs.  The Spanish captured the first "Sir Thomas Pasley".  The second had a brief, but highly productive, career that later led to her crew qualifying for the Naval General Service Medal.  After she was returned to her owners in March 1802, she may have been wrecked in the Mediterranean that same year.
