Question: Dominic Mancini, was an Italian who visited England, in 1482-3, he wrote a report, and called it, The Occupation of the Throne of England by Richard III, was a King of England from 1483 until his death in 1485, at the age of what number, in the Battle of Bosworth Field?

Nicholas Gainsford, also written Gaynesford or Gaynesforde, (about 1427–1498) of Carshalton, Surrey, of an armigerous gentry family established at Crowhurst, was a Justice of the Peace, several times Member of Parliament and High Sheriff of Surrey and Sussex, Constable and Keeper of Odiham Castle and Park, Hampshire, who served in the royal households from around 1461 until his death in 1498.  Rising to high office during the reign of Henry VI, he was an Usher to the Chamber of Edward IV and, by 1476, to his queen Elizabeth Woodville.  Closely within the sphere of Woodville patronage, he was a favourer of Edward V, and was a leader in the Kentish rising of 1483 against Richard III.  He was attainted in 1483, but was soon afterwards pardoned, and fully regained his position and estate as Esquire to Henry VII and Elizabeth of York after the Battle of Bosworth Field.  He established the Carshalton branch of the Gainsford family. <SEP>  He was the last king of the House of York and the last of the Plantagenet dynasty. Richard III (2 October 1452 – 22 August 1485) was King of England from 1483 until his death in 1485, at the age of 32, in the Battle of Bosworth Field.  His defeat at Bosworth Field, the last decisive battle of the Wars of the Roses, marked the end of the Middle Ages in England.  He is the subject of the historical play "Richard III" by William Shakespeare. <SEP>  He called it: "De Occupatione Regni Anglie per Riccardum Tercium" ("The Occupation of the Throne of England by Richard III"). Dominic Mancini was an Italian who visited England in 1482-3.  He witnessed the events leading up to Richard III being offered the English crown.  He left in 1483 and wrote a report of what he had witnessed.  The account is a major source of information about the period, but it sat unread in a French library until rediscovered in 1934. <SEP> 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.
