Edward Bayntun was born at Bromham House and baptised on the 5th September 1593, at Bremhill, in the county of Wiltshire and matriculated at Christchurch, Oxford on the 27th April 1610. Many documents refer to him as Sir Edward Baynton, however his memorial stone is clear evidence that the family changed the spelling of their surname to Bayntun sometime around the beginning of the 17th century.

In 1613 Edward married Elizabeth Maynard, the daughter of Sir Henry Maynard of Easton, Co. Essex, who was made Lord of Easton when the manor was granted to him by Queen Elizabeth I in 1589. Sir Henry was also Secretary to the distinguished Minister of the Queen, Lord Burleigh and was one of the representatives of St. Albans in Parliament.

Edward and Elizabeth had nine children, some of which died at a very young age. Twins, Elizabeth and Lucy, were born in 1615, but did not survive long. Elizabeth died as an infant and Lucy was just seven months old when she died. Their first son, Henry, was born two years later in 1617 but died at the age of just two. In 1618 they had a second son, which they called Edward and when Henry died in 1619, Edward became heir.

The name Henry must have been very important to Sir Edward and Elizabeth and no doubt the first born Henry was named after Sir Edward's father. in 1621 another son was born and he too was christened Henry. Anne was born in 1622 and another son, Charles born in 1624, who died as an infant. In 1625, William was born but he too died young at just four years of age. Their last child, Mary was born in 1628.

After the death of his father, Sir Edward Bayntun in 1616, Edward inherited the Manor of Bromham.

He was M.P. for Devizes in 1614, 1637 and again in 1640, M.P. for Wiltshire County in 1621-22, M.P. for Chippenham 1626 and again from 1640-53. He was High Sheriff of Wiltshire in 1637-38 and a Commissioner in the Trial of Charles I but did not act. His hostility to the court manifested, that in the Protestation of 1640, his name appears second in the list, being the first after that of Mr. Speaker Lenthall.

Evidence exists in town records that King James I visited Sir Edward's house at Bromham three times in 1618, 1620 and stayed there again from 29th to 31st July 1623. In 1618, the Chamberlain's books from the Devizes Corporation show that certain items were lent to Sir Edward for this visit to Bromham House and that the Corporation paid for the wine given to the King's Trumpeters.

A deed dated the 20th March 1624 shows that Sir Edward was a founder of the Salisbury Races, and to stimulate its continuance, he established a silver cup to be ran yearly, in the days of King James I, which after his death, was continued under the trusteeship of the Mayor of the town.

Between 1625 and 1630, King Charles I set up schemes for disafforestation in order to raise money. The cleared land was then enclosed and sold. This caused great hardship for those living on the edge of the forests and there was much conflict with the authorities. This "Miniature Civil War" was marked by a noticeable lack of co-operation towards the authorities by influential people, including Sir Edward Bayntun, who refused the Sheriff's call for assistance, telling him "that he did not much fancy that service".

In 1631 Edward Bayntun was awarded the title Knight Bachelor of Wiltshire.

He was evidently a quarrelsome man with an arrogant and uncertain temper and for much of the history of the Civil War in Wiltshire we hear of his angry rivalry with his neighbours, particularly Sir Edward Hungerford. Many on his own side thought him treacherous and was generally regarded with suspicion and even his public career, both in County Government and as an M.P. was fraught with disputes.

In 1633, the Manor of Avebury, with lands at Catcomb which were attached to it, were purchased by Sir Edward from William Dunch. He conveyed it to his son Robert – one of the twins born to his second wife Mary. Robert eventually sold Catcomb in 1682 to Matthew Barley of Lockerley, Hants. It was known then as the Manor of Catcomb and separate to the original Manor of Avebury.

Also in 1633, a government agent trying to carry out a Royal Commission on the clothing industry complained bitterly of the obstruction offered at Bromham by Sir Edward Bayntun.

Sir Edward's wife, Elizabeth, died on 30th March 1635 and he later re-married Mary Bowell of Cokethorpe, Oxfordshire at St. Peter Paul's Wharf, London on 30th March 1640. She is thought to have been the daughter of Nicholas Bowell (1568-1623) of Chesterton, who was a Yeoman of the Great Chamber. Mary bore him three children – a girl (who died young) and twin boys, whose names are mentioned on their mother’s monument (see description at bottom of page).

In October 1642 he became Commander-in-Chief for Wiltshire County and he commanded a force for Parliament in the early part of the Civil War and was a Commissioner of the English Parliament to reside in the Scots Army. Devizes was fortified by Sir Edward for parliament and its magazine enlarged.

Sir Edward's nomination to so important a post in the county of Wilts was manifestly dictated by feelings of personal regard, with him having already held military office under two Earls of Pembroke for 20 years past. Though he was not destitute of the influence which wealth and long standing in the county gave to his family, yet the reputation which he at the same time bore among good fellows, or as they were then termed "roaring boys", seems to have been felt as unfitting him for the post of leader at so momentous a crisis.

Such at least may be gathered from the newspaper reports. It was not therefore without a certain basis of truth that a set of charges were levelled against him from some private press, in the form of a letter purporting to be written by a Devizes burgess, and representing Sir Edward's coduct in the town as capricious, tyrannical and unpopular.

That the entire letter, as such, was a forgery, there can be no doubt; though it was possible enough that its sentiments were held by some of the townsfolk; and equally credible that the actions attributed to Bayntun were matters of fact, such as his committing the Mayor to prison for uttering the King's proclamation, punishing a boy for firing a squib and causing the Borough Officials to be placed in the stocks which he had just ordered them to repair.

In January 1643, Parliament passed an Ordinance to raise two regiments of horse and one regiment of dragoons in Wiltshire under Sir Edward Bayntun (the new Commander-in-Chief) to secure the county against invasion from Oxford.

Soon after, Sir Edward Bayntun withdrew from active soldering after a quarrel with his neighbour and fellow Commander, Sir Edward Hungerford, arising mainly from a lack of co-operation in the critical hour, but no doubt, springing originally from the jealously of rival aspirants for the supreme command of the Wiltshire militia. He subsequently made approaches to the King (for which he was imprisoned for some time in the Tower). To enflame matters even more, Hungerford was then appointed Commander-in-Chief of parliament's forces in Wiltshire in place of Bayntun.

Some time prior to the destruction of his house by the fire, Sir Edward had the good sense to seek a securer asylum for his treasures than Bromham House and transferred the bulk of his moveable personal property, consisting of nine trunks full of plate and money to the Isle of Wight, at the time under the government of the Earl of Pembroke.

Whilst there he made some unkind remarks about his former comrades and as a result, Lieutenant-Colonel Carne, Lord Pembroke's Agent, was sent to arrest him. Carne, at the time, wrote: No man hath a fouler mouth than Bayntun for slagging off his comrades.

Bayntun was imprisoned in the Tower for a while but was eventually released on the 19th September 1643 to his residence, upon his promise to be a true prisoner to the House. Then on the 24th August 1644 the House of Commons ordered that he have restored unto him all such goods as were seized of his in the Isle of Wight and that all restraint, formerly laid upon them, be taken off.

But this did not save his family residence at Bromham House from being taken and burned to the ground by Royalist Forces from Devizes on 5th May, 1645. If he was guilty of treachery it was ironical that the great house at Bromham should have been burnt down by Royalist troops.

Bromham House had been empty for some time and it's destruction was deliberate vandalism to prevent it being occupied by the Parliamentary forces. It did nothing to help the Royalist's cause and Colonel Lloyd (Governor of Devizes and Royalist), with a party of horse and foot, came from Devizes to Bromham and utterly destroyed, by fire, one of the most famous buildings in Wiltshire. Sir Edward's other house at Bremhill was also set alight by the Royalist troops and they drove off over 600 of his sheep.

After the destruction of Bromham House, the family moved into a smaller house Sir Edward bought, called Spye Park Lodge, to the north of Bromham village and by 1654 Sir Edward had this house enlarged and decorated with carved masonry taken from the ruins of the old house and added some very rich furniture.

But before any rebuilding took place, he petitioned for the confirmation of his title to the manor which had been claimed by the Commonwealth Commissioners as having belonged to the Bishop of Salisbury. Sir Edward said that he had lost all his deeds as evidence of ownership when the Royalist's burnt down his houses at Bromham and Bremhill during the Civil War.

At this time Bowood Forest was disparked and Sir Edward was granted the deer and it was said they were driven home through a lane made by the weavers with their cloth. The Parliament proceeded to sell the lands which had belonged to the Bishops and amongst these were some at Bishops Canning which Sir Edward claimed as a portion of his estates. The House admitted his title to the Bromham estate, but desired further evidence about the lands at Bishops Cannings

John Evelyn mentions in his famous Diaries that he visited the house on the 19th July 1654 before it was completed. He says of his visit: We went to Sir Edward Bayntun's Spye Park House, north of Bromham village, a place capable of being made a noble seat. But the humorous old Knight has built a long single house of two low stories on the precipice of an incomparable prospect and landing on a bowling green in the park. The house is like a long barn and has not a window on the prospect side.

This was where the family continued to live until the mid-19th century. The gateway that was erected at the entrance to Bromham House, as a gift from Catherine of Aragon, had escaped the fire and Sir Edward had it carefully dismantled and re-built once again, on it’s third site, at the entrance to the new house at Spye Park. It stands today as the only evidence of the Bayntun's two fine houses. Originally the gateway was the entrance to Stanley Abbey and is now known to locals as Spye Arch.

The tything of Chittoe adjoined the parish of Bromham, but was an outlying part of the Manor of Bishop's Cannings, of which the larger part belonged to the Spye Park estate. This entire manor was purchased by Sir Edward by an underlease from Mr. Robert Henley, Lord Farmer at the time, and this included all rights and property in Chittoe. This comprised of about 100 acres of waste which were added to the new domain called Spye Park, a condition being annexed that day by way of acknowledgement, that Bayntun would pay to the Bishop, as Chief Lord, an annual contribution of two fat bucks.

The Spye Park estate paid to the Vicar of Bishop's Cannings every year £2 - 6s - 8d, which may have been the value of the tythes in ancient times, when nearly all the land in tything was waste. A 13th century deed, or Inspeximus, shows the whole of the tythes of this part of the parish were given to the Vicar of Bishop's Cannings and there had previously been an ancient chapel on this land, long since demolished.

There is a monument commemorating Mary Bowell, Sir Edward's second wife, in the South Chapel in St. Marks, or the Lord Mayor’s Chapel – also called the Chapel of the Hospital of the Gaunts, in perhaps the most ancient church in Bristol.

This Baroque style monument shows Dame Mary Bayntun (Mary Bowell) with her two sons kneeling each side of her on pedestals, beneath triple domes holding open draped curtains. The monument was originally in the crossing arch under the tower, but was moved to its present position when renovations were made in the 19th century.

Sir Edward Bayntun had land at the time in Barton Regis (that was the name given to the area directly outside the old city of Bristol) in the Lawrence Hill area, which is about 30 miles from Bromham. As this land had been land owned by the Gaunts, she qualified for burial in St. Mark's.

There is no other connection between the Gaunts and the Bayntuns. If such had existed, and any of the latter family had, from this cause, used the Mayor's Chapel as a burying-place, surely it would have been some of the earlier male representatives and not merely the second wife and relect of one of them as late as 1667.

It is most likely Mary Bowell resided in Bristol after her husband's death, through some connection of her own family with the city. It is also thought that one of her sons was a merchant or possibly Mayor of Bristol which would also account for her burial there.

The Latin inscription on Dame Mary Bayntun's tomb reads:
Memoriae sacrum hic sita sunt ossa ornatissimae faeminae, Dominae Mariae Dom. Edwardi Baynton, nuper de Bromham in comitatu Wiltoniae relictae. Faemina fuit ad antiquum morem composita, illibatae vitae, pietati, forma et omni laude maternali virtute muliebri ornata, suam postquam vitam nimis eheu brevem nec a molestiis penitus liberam, piam, fidam, pudicam, castam, generosam hospitalitate caritate, aliisque quam plurimis virtutibus excultam omnibus, etiam egenis, caram egisset. Eam cum ingenti omnium utriusque sexus, quibus aut fama aut facta nota fuit, luctu ac dolore reliquit, pro faeliciori commutavit, et Christo placide obdormivit aetas suae 44, Anno Dominini MDC secundo. Sordes terra tenet, tenet ingens spiritus aethra aetherosque locos. Hic restant ossa sepulta. Huic eius filii gemini dom. Robertus et dom. Nicolaus, quos suo utero conjugali peperit fructifero posuere momentum.

The English translation is: These bones are placed here as a thing sacred to the memory of a most well-endowed woman, Lady Mary, lately the relict of Sir Edward Bayntun of Bromham, Wiltshire. She was a woman framed according to ancient custom, of a spotless life, endowed with piety, beauty, and every maternal praise and womanly virtue, after having led a life, alas, all too brief and not free of troubles, a life that was faithful, modest, chaste, and noble with hospitable charity and ornamented by as many virtues as possible, dear to all men, even the needy. When she exchanged this life for a happier one, to the great grieving and sorrow of all those to whom she was known by reputation or deed, she slept peacefully in Christ in the 44th year of her life, Anno Domini 1602. Earth possesses her offscourings, but her great spirit possesses heaven and the heavenly places. Here repose her buried bones.

However, either the inscription or the transcript of it is incorrect with regard to Dame Mary's year of death. The correct date is 1667, not 1602. This fine monument was the work of Danish sculptor, Caius Gabriel Cibber (1630-1700).

Sir Edward Bayntun's last will was dated 31st October 1657, and reads:
In the name of God, Amen. I Sir Edward Bayntun of Bromham in the county of Wiltshire, knight, being weak in body but sound in memory and perfect in mind (praise and thanks be given to God therefore) do hereby and herein make this my absolute last will and testament in manner and form following. And first I bequeath myself into the hands of my maker, hoping to be saved and redeemed only by the death and passion of his son, my saviour Jesus Christ, beseeching God now and at all times hereafter to prepare my heart by faith in him for evermore. And when it shall please God to call me to his mercy, grant that I may be then and at all times ready and willing to render up myself unto life everlasting. And first for my body, I commend it to the earth from whence it came, there to remain until the resurrection. And as for those worthly goods and estate [sic] which it hath pleased God to bless me withal, I give and dispose of the same in manner and form following. First, whereas I have by some former deed (which I cannot now find settled on my second son Henry an annuity of £200 by the year to be issuing, levied, had, received, and taken out of my manor of Bromham for and during his natural life, my will is and I do hereby desire my eldest son Edward to confirm the same annuity unto him that he may enjoy the same according to my intent. I give to my son Nicholas (one of the twins born to his second wife Mary Bowell in 1649) £500 to be paid within three months of my decease. Also I desire my eldest son Edward to take care of my daughter Mary (his youngest daughter, perhaps unmarried at the time) and to provide for her not to suffer her to want such things as shall be necessary for her. Also I make and ordain my well-beloved wife and my son Robert (the other twin of the above) to be the executors of this my last will and testament.
Witnesses: William Johnson, Peter Arnault, Samuel Horsington.

The marble stone on the north side of the Beauchamp chapel, in the Church of St. Nicholas, honouring Sir Edward Bayntun reads: Sir Edward Bayntun, knight, son and heir of Sir Henry Bayntun Knt. Obit 18 Dec. 1657.

When Sir Edward Bayntun died on 18th December 1657 he was succeeded by his eldest son and heir Edward Bayntun
