Sir John Seymour, Knight banneret (c. 1474 – 21 December 1536) was an English soldier and a courtier who served both Henry VII and Henry VIII. Born into a prominent gentry family, he is best known as the father of Henry VIII's third wife, Jane Seymour, and hence grandfather of king Edward VI of England. Family The Seymours were descendants of an Anglo-Norman family that took its name from St. Maur-sur-Loire in Touraine. William de St. Maur in 1240 held the manors of Penhow and Woundy (now called Undy) in Monmouthshire. William's great-grandson, Sir Roger de St. Maur, had two sons: John, whose granddaughter conveyed these manors by marriage into the family of Bowlay of Penhow, who bore the Seymour arms; and Sir Roger (c. 1308 – before 1366), who married Cicely, eldest sister and heir of John de Beauchamp, 3rd Baron Beauchamp. Cicely brought to the Seymours the manor of Hache, Somerset, and her grandson, Roger Seymour, by his marriage with Maud, daughter and heir of Sir William Esturmy, acquired Wulfhall (or Wolf Hall) in the parish of Great Bedwyn in the Savernake Forest, Wiltshire. Sir John Seymour was a great-great-grandson of this Roger Seymour. Sir John Seymour was born around 1474, the eldest son of John Seymour (c. 1450 – 26 October 1491) of Wulfhall, by his marriage to Elizabeth Darell (or Darrell) (born c. 1451). He married Margery, the daughter of Sir Henry Wentworth of Nettlestead, Suffolk, and his wife Anne Say. Anne was the daughter of Sir John Say and his wife, Elizabeth, daughter of Lawrence Cheney (or Cheyne) (c.1396–1461) and Elizabeth Cokayne. Margery Wentworth's grandfather, Sir Philip Wentworth, had married Mary, daughter of John Clifford, 7th Baron de Clifford, whose mother Elizabeth was daughter of Henry Percy (Hotspur) and great-great-granddaughter of Edward III. Margery was renowned for her beauty as well as her quiet and gentle demeanour, and she came to the attention of the poet John Skelton. Career Seymour succeeded his father in 1492 and was knighted in the field by Henry VII for his services against the Cornish rebels at Blackheath on 17 June 1497. He was made Knight banneret in 1513. He was present at the sieges of Thérouanne and Tournay in 1513 as well as the two meetings between Henry VIII and Francis I: the Field of the Cloth of Gold in 1520, and again in 1532.
