Edward III (13 November 1312 – 21 June 1377) was King of England from 25 January 1327 until his death; he is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II.
 Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe.
 His long reign of 50 years was the second longest in medieval England and saw vital developments in legislation and government—in particular the evolution of the English parliament—as well as the ravages of the Black Death.
John (de) Charleton (or (de) Cherleton or (de) Charlton or (de) Charlestone), 1st Baron Cherleton, 1st Lord Charlton of Powys (1268–1353) came from a family of minor landowners near Wellington, Shropshire.
 He was the son of Robert de Charleton (and elder brother to Alan, and Thomas, Bishop of Hereford) of Apley castle near Wrockwardine.
Sir William de la Pole (died before 1319) was the fourth son of Gruffydd ap Gwenwynwyn and would have inherited the principality of Powys Wenwynwyn, if it had continued to descend in the male line according to Welsh law, instead of having been surrendered to Edward I and regranted to his father as a marcher lordship.
 This descended (according to English law) to William's elder brother Owen de la Pole, and after the death of his son without issue to his daughter Hawise Gadarn, Lady of Powys, wife of John Charleton, 1st Baron Cherleton.
 Contrary to a few reports, there is no evidence of any relationship to William de la Pole of Hull, merchant and financier to Edward III.
Edward Charleton (or Cherleton or Charlton), 5th Baron Cherleton, KG (1370–1421), 5th and last Lord Charlton of Powys, was the younger son of John Charlton, the third baron, and his wife, Joan, daughter of Lord Stafford.
Sir John de Sutton II (1310 – 21 November 1359) was the first Baron Sutton of Dudley, who was summoned to the Parliament of England in 1342.
 He was the son of John de Sutton who inherited Dudley Castle by marriage to Margaret, daughter of Roger de Somery.
 John II married Isabella (d.10 April 1397), daughter of John Charleton, 1st Baron Cherleton, before 1329.
 He was succeeded by his only son Sir John de Sutton III (1338-1370), 2nd Baron Sutton of Dudley.
 Upon the death of John II, possession of the Castle Dudley was vested to his wife Isabella from 1359 to 1397.
Hugh Everard Wedgwood, 3rd Baron Wedgwood (20 April 1921 - 25 April 1970) was the third Baron Wedgwood of the pottery dynasty.
 He was the son and only child of The Hon. Francis Wedgwood (later 2nd Baron) and his wife Edith May Telfer, daughter of William Telfer of Glasgow.
 He was the great-great-great-great-grandson of the potter Josiah Wedgwood.
 Like his father, he was educated at Bedales School.
 During the Second World War he served as an officer in the Kenya Regiment.
 In 1949 he married Jane Weymouth Poulton, daughter of W.J. Poulton of Kenjockety, Molo, Kenya; they had one son, Piers and two daughters.
 He was a farmer in Hillwood, Molo, Kenya, 1941–1964.
 Upon his father's death in 1959 he succeeded his father as the 3rd Baron Wedgwood.
 Upon his own death in 1970, the Barony passed to his son Piers.
He is reported in the muster rolls for 1372 as being of the rank of Banneret leading 22 archers and men-at-arms on a naval expedition under the leadership of King Edward III.
Baron Cherleton is an abeyant title in the Peerage of England.
 It was created in 1313 when John Charleton was summoned to Parliament.
 The Charleton family were a Shropshire knightly family, one of whom married Hawise "Gadarn" the heiress of the Lordship of Powys.
 This was the former Welsh Principality of Powys Wenwynwyn, which had as a result of the last prince's submission to Edward I been transformed into a marcher lordship.
 The title fell into abeyance on the death of the fifth Baron in 1421.
Alice FitzAlan, Baroness Cherleton (1378–1415) was an English noblewoman, being the daughter of Richard FitzAlan, 11th Earl of Arundel.
 She was the wife of John Charleton, 4th Baron Cherleton.
He succeeded to the titles of 4th Baron Cherleton and 4th Lord of Powys (Feudal baron) on 13 July 1374, on the death of his father, John Charleton, 3rd Baron Cherleton, and held the office of Justice of North Wales from 20 March 1387.
