Sir Hugh Calveley (died 23 April 1394) was an English knight and commander, who took part in the Hundred Years' War, gaining fame during the War of the Breton Succession and the Castilian Civil War. He held various military posts in Brittany and Normandy. He should not be confused with his nephew, also Sir Hugh Calveley, who died in June 1393 and was Member of Parliament for Rutland. Background Hugh Calveley was born the youngest son of David de Calveley of Lea, and his wife, Joanna. His name is frequently misspelt as Calverley, Caverle, Calvelegh, Kerverley, Calverlee, Calvyle, Kalvele, Calviley, and Calvile. The family held the manor of Calveley in Bunbury, Cheshire, living in Calveley Hall. The Hall came into the possession of the Davenport family through marriage in 1369. Hugh was likely born at Lea Hall in Lea Newbold, formerly a civil parish, now in the parish of Aldford and Saighton in the Borough of Cheshire West and Chester. Lea Hall remained in the Calveley Family until 1714 and was demolished in about 1876. Estimates of the year of his birth range from 1315 to 1333. Calveley married an Aragonese princess, the Dna Constanza. The evidence is incontrovertible, as there is a letter of 1377 in existence from Pedro IV on the subject of her dower. How long they cohabited if at all is a moot point but it is known that the princess left Calveley. The date of her departure is unknown, but Pedro wrote to his son Martin in 1381 ordering him to stop living in adultery with her. It is possible that he was a close relative, maybe even a half-brother, of Sir Robert Knolles. Breton civil war Along with many other Englishmen, the young Hugh Calveley served in Brittany, supporting Jean de Montfort's English-backed bid to become Duke of Brittany against the French-backed claimant, Charles de Blois, during the Breton War of Succession. An anonymous Breton poet's account of the Battle of the Thirty in 1351 has "Hue de Caverle" as a knight fighting on the English side (where he was defeated, captured, to be ransomed later). One estimate of the date of his knighthood is 1346, though documents from 1354 do not refer to him as a knight, and there is some evidence that he was not knighted until 1361. In 1354, Calveley was captain of the English-held fortress of Becherel. He planned a
