Nicholas Bayntun was born in 1382 at Faulston House, in the County of Wiltshire. Deeds relating to him show his name listed as Nicholas Benton and in other documents as Beynton, however we see the spelling of the surname changing to Bayntun by the beginning of the 17th century.

Records show he was Lord of the Manor of Fallerston (Faulston) and also of part of the Manor of Compton Chamberlayne in the next valley to the North, the Nadder. Deeds dated 12 Henry IV (1411 - Wilhelma de la Mare's will) and 9 Henry V (1422 - his own will), show Nicholas de Benton in possession of lands at Compton Chamberlayne.

Nicholas' marriage to Joan de la Roche (his second cousin), was arranged by his father and Dame Maud de la Mare, his wife's grandmother. This contract was made at Steeple Lavington, in Wiltshire, on the Feast of St. Alban the Martyr. This marriage had an important effect upon the subsequent fortunes of the Bayntun family. Joan was the daughter of Sir John de la Roche and his wife, Wilhelma de la Mare – a very important and wealthy family from Bromham, Wiltshire. An Indenture, being the memorandum of agreement between Dame Maud de la Mare and Nicholas Bayntun, the father, that Nicholas Bayntun, son and heir of the said Nicholas, shall take to wife Joan, the daughter of Sir John Roches, Knight and Wilhelma his wife, and the said Nicholas, the father, shall give to the said Nicholas and Joan the Manor of Ayschcame, in Somerset and the Manor of Nether Worfton, in Wiltshire and 10 Marks yearly rent in the Manor of Compton Chamberlayne, in Wiltshire, until such time as he shall have possession of the Manor Tabelershall, in Sussex, which Manor he shall give to the said Nicholas and Joan after the decease of his sister Cecily who holds the same for her lifetime, to hold the same to them and the heirs of their bodies with remainder as to the Manors of Ayschcame and Nether Worfton to the said Nicholas, the son, his heirs and assigns, and as to the Manor of Tabeleshall to the right heirs of Nicholas the father. Further the said Nicholas, the father, shall before the Feast of St. Peter's Chains enfeoff such persons as he pleases of the Manors of Chilton Candover and Wyke Daundele, in Hampshire and the Manor of Compton Chamberlayne, in Wiltshire, on condition that they shall re-enfeoff him thereof for the term of his life, with remainder after death to the said Nicholas and Joan and the heirs of their two bodies begotten forever, with remainder in default as to the two manors of Chilton Candover and Wyke Daundele to the right heirs of Nicholas the son, and to the Manor of Compton Chamberlayne to the right heirs of Nicholad the father.

We learn from the Calendar of Patent Rolls, that Joan and Nicholas had four daughters – Agnes, Alice, Eleanor and Isabel and one son, John, who became his father's heir.

After the death of Joan's father, Sir John de la Roche, in 1400, his property had been divided among his co-heiresses. Joan's sister, Elizabeth, received the Manor of Bromham Roche, which would eventually be inherited by the Bayntun family in 1508.

The Manor of Whaddon was owned by Sir John de la Roche and was also passed onto Elizabeth and her sister, Joan, at the time of their father's death, but eventually it fell entirely to Elizabeth. This Manor, like the Manor of Bromham, was later passed onto the Bayntun family after the death of Lord St. Amand in 1508.

The Manor of Horton and the Manor of Chittoe were others inherited by Nicholas Bayntun as laid out in the terms of Wilhelma de la Mare's will. Wilhelma was the wife of Sir John de la Roche and died on the 31st October 1410. At this time the Royal Escheator in Wiltshire was ordered to assign to her daughter, Elizabeth and her husband, Walter de Beauchamp, rent of 13s - 4d issuing from lands in Chittoe whereof Geoffrey Driffelde was tenant for life. Nicholas Bayntun and his wife Joan, the other de la Roche heiress, gave assent to this.

Apart from lands bequeathed to Elizabeth and Walter, they also received the wardship of other lands which Wilhelma left to her four-year-old grandson, John Bayntun, the son of the above mentioned Nicholas and Joan.

A deed dated 14 Henry IV (1413) witnessed by Oliver Cervington, Henry Gilbert, Thomas Meriel and Thomas Martin also referred to Nicholas Benton as Lord of the Manor of Fallerston.

Nicholas Bayntun, of Bishopstone, in the county of Wilts., gentleman, was mentioned in the Calendar of Patent Rolls, Henry V – 1416-1422, for not appearing before the Justices of the Bench to answer a plea that he render £4 to William Algar, Clerk, and William Lord, executors of the will of Richard Spencer, late citizen of Salisbury and Edith, the wife of Richard Spencer. This was issued on the 15th October 1417, at Westminster.

Nicholas Bayntun died in February 1422 and his wife Joan is said to have survived him and was re-married in 1429 to William Whaplode M.P., of Chalfont St. Peter, Co. Buckinghamshire. At the time of her marriage she conveyed the Manor of Faulston to her son, John, and he in turn, is said to have conveyed the Manor of Week to his mother for life.

The Calendar of Patent Rolls, Henry V - 1416-1422, dated the 19th February 1422, at Westminster, mentions Robert Forster, Robert Pokeswelle, John Whytehorn and John Gilberd, having lately acquired to themselves and their heirs from Nicholas Beynton, now deceased, the Manor of Compton Chamberlayn, in the county of Wilts, held of the King in chief, and entered thereon and afterwards granted it to Joan, the wife of the said Nicholas, for life with successive remainders to John Beynton, his son and heir, and the heirs of the body of the latter, Agnes Beynton, Alice Beynton, Eleanor Beynton and Isabel Beynton, the daughters of Nicholas and Joan, and the heirs of their bodies, and the right heirs of Nicholas and Joan entered thereon, without licence; the King for £10 paid in the hanaper, pardons the treaspasses in this.

Nicholas Bayntun's estates in Sussex, Hampshire and Wiltshire were the subjects of Inquisitions Post Mortem. That for Sussex was held at Horsham on the 29th May 10 Henry V (1422) and the jury found that some time beore the day of his death Nicholas was seised in fee of the Manor or Taberlershalle and appurtences in Shepele, Westgrynsted and Thackham which he had given on the 27th July, 7 Henry V to John Arundell, Knight, Lord of Arundell and Mautravers, John Burgh, esq., William Ryman and Philip Marshall, their heirs and assigns in perpetuity and that the said Nicholas died on the 15th January in the ninth year of King Henry V (1421/2) and his next heir was his son John Bayntun, 16 years of age on the day of March next after the Feast of the Holy Trinity last past.

There is no record of the burial place of Nicholas Bayntun, but it is thought he and his family before him, may have been buried in a square field, known as Chapel Close, which might have been either the site of a chapel or a field attached to the chapel which was next to Faulston House. There are no visible signs of any graves today, unless buried beneath the ground.

When Nicholas Bayntun died he was succeeded by his eldest son and heir Sir John Bayntun
