Of Anthony's seven sons, apart from John who lived in Staffordshire and succeeded his uncle as steward of the family estates, we have information only about Thomas, the eldest to survive infancy, and Leonard both of whom were born at Rosegarland. They had completely different temperaments, Leonard being impetuous, excitable and irascible whilst Thomas was cool, calculating and long-sighted. Even before their parents' death they were quarreling over which of them would possess the Agard Hackney mansion under the terms of their mother's marriage settlement, and Sir Anthony had to include in his will a proviso that if they engaged in litigation over the Hackney property both would forfeit all rights under the will. On his marriage to Honora, daughter of William Walsh of Blue Cranach, Lord of the Walsh Mountains, Leonard had moved from Tintern and taken up his residence at Ballyknocken in Queens County. He was High Sheriff of Wexford in 1596. Unfortunately troubles in Wexford were not so far away from Ballyknocken as to prevent his participation. The policy of pacification had long since broken down and in 1596 full-scale rebellion engulfed Wexford. At Enniscorthy a battle occurred in 1597 and in a report to the Privy Council on the insurrection Lord Justices Loftus and Gardner state that Leonard Colclough, the second son of Sir Anthony, "was cruelly slayne and his brother Sir Thomas Colclough sore wounded in two places in his arm and his horse was slayne under him......." From the report it seems that the disastrous outcome of the skirmish in which a British force of over 400 was able to inflict only half-a-dozen casualties on the Irish was due to the foolhardiness and lack of discipline of Leonard Colclough. A special report to Burleigh also dealt with Leonard's death.

In 1615 he sold Staffordshire land in Hanley, Whistoneaves, Lees, Lockwood, Kingsley, Thoresby, Newcastle, Cheadle, Blurton and Fossbridge and a further 500 acres in the same places in the following year and, in 1618 he bought 610 acres in Wemborne, Orter, Woodford, Longdon, Elmhurst and Bilston for £800. In 1623 on the marriage of his eldest son Adam to Alice, daughter of Sir Robert Riche, he and John, his youngest brother who had been acting as steward to the Staffordshire estates, transferred 1090 acres to Sir Robert as trustee for Alice's marriage settlement. In that year, too, his dealings in tithes from 'impropriate rectories' brought him in £900. For the next 200 years "impropriate rectories" and the tithes from them formed a major part of the family's investments and disputes over them made no small contribution to the incomes of the family's lawyers.

"...indeed it was not free from doubt as to what religion Adam Colclough professed; as a race the Colcloughs were reckless and regardless of religion; sometimes they were Catholics and sometimes Protestants..."

It might be mentioned that there were also Quakers amongst them and the three chests each containing a quarter of a million pieces of eight found under the bed of the Quaker John Colclough (though he may possibly have been a Coakley) when he died in Trinidad in the 1800s were certainly the proceeds of successful piratical operations on the Spanish Main.

On the death of Sir Thomas in 1626 the Tintern estates together with what was left in Staffordshire and the Hackney house went to his Protestant children and the Duffry to the Catholics. In addition to his purchases and mortgage-foreclosures in the Duffry - the 'Black Lands' round Mount Leinster - Sir Thomas had also managed to obtain grants from the Crown which included Monart and Mochurry and it was here that his grandson Patrick built the magnificent Duffry Hall in 1685. When Leonard's son Anthony married Ismay Browne of New Ross Sir Thomas gave them the title to Ross Castle as part of the marriage settlement but having something of his father's temperament Anthony got into financial difficulties. He borrowed money on the security of a mortgage of the castle which after the inevitable foreclosure passed into the possession of Alderman Abel Ram of Dublin.

Sir Adam, the first baronet, was by Colclough standards of eccentric behavior a nonentity. He purchased the baronetcy by a contribution to the costs of the plantation of Ulster and though he held land in Clonmines by knight-service the closest he ever came to involvement in military activities was in 1631 as a member of the bench of justices called upon to deal with a disturbance involving the soldiery at Duncannon Fort and the crew of the ship 'Fifth Whelp'. Apart from this and the fact that he was appointed guardian to Henry Laffan, a 13-year old Catholic ordered by the court to be given a Protestant up-bringing, there is little recorded about him. He had trouble with his investments in impropriate rectories and continued his father's policy of running down the Staffordshire estates, selling a further 220 acres of land in Blurton and Cocknage to Samuel Bagnall and William Norman for £60 and 150 acres in Newcastle for £160. In 1635 Sir William Brereton accompanied by a Mr Flood and a Mr Griffiths visited Tintern and recorded that he was exceedingly kindly and courteously entertained by Sir Adam and that "this is a very fair large and stately house and of great receipt. He keeps a good house and a great estate here and his lady is a dainty, complete, and well-bred woman. She is Sir Rob Riche's daughter." to which Flood and Griffiths added

"Sir Adam keeps a good and hospitable board well supplied and well attended and is to all a most warm-hearted and courteous gentleman."

Brereton mentioned that Sir Adam told them that he had dined in Milford Haven in Wales and supped in Wexford the same evening.

Sir Adam had married Alice, daughter of Sir Robert Riche, Master in Chancery, at Tintern on 26 March 1623 and she certainly seems to have been the dominant partner. The Riches were an Essex family and also had a mansion at Hackney where contact between the two families probably arose. Alice's grandfather had been Lord Chancellor to Henry VIII.

The ferocity with which the Long Parliament had set about the suppression of the endemic risings in Ulster resulted in 1641 in a conflagration involving the whole country which remained in a state of confused warfare, first against the Royal forces and then with the King as an ally against the Parliamentarians and then against Cromwell's genocidal mania until the Restoration. The Colclough contribution was the attack on Tintern Abbey led by Alice's three brothers-in-law, Dudley of Monart, John of Pouldarrig and Anthony of Rathlin, at the head of a large rebel force. On the outbreak of the rebellion Alice, whose husband had died four years previously and whose only son Sir Caesar was a schoolboy at Westminster School, had put the Abbey in a state of defence, prepared it as a place of refuge for the Protestant inhabitants of the neighbourhood (over 200 of whom sheltered within its walls during the subsequent siege), arranged for it to be garrisoned by a detachment of troops from Duncannon Castle under the command of Major Aston, and then left for England. She took with her such of the Protestant gentry as had homes in England to go to, and in the proceedings after the suppression of the rebellion a specific offence charged against many of the Protestants who had participated was that they had not gone to England with Lady Colclough.

Dudley's brothers John and Anthony of Rathlin were both Protestants though Anthony had taken the oath of the Catholic Confederation and had been a member of the Supreme Council at Kilkenny in 1642, so neither suffered any detriment through having been a rebel. John in fact had the benefit of being allowed to remain for the rest of his life in occupation of Tintern Abbey where the rebels had put him. Anthony of Rathlin had two sons of whom the elder, Adam of Grays Inn, ranks with Thomas the King's Sergeant to Edward I and Sir Anthony as one of the outstanding members of the family. All that Burke has to say about him is that he was a barrister and that he married the daughter of Col. Thomas Blague, Groom of The Chamber to Charles II, Mary, maid of honour to Anne, Duchess of York and disliked by the French diarist de Grammont because of her "paupieres blondes" (blond eyelashes)! Adam was appointed Clerk of the Green Wax, an office which in the hands of previous holders had been a sinecure. He turned it into a kind of Ombudsman, imposing a reign of terror over corrupt judges and court officials, who regarded fines and court fees as perks to be shared between them. On one occasion he was at Lewes Assizes on Monday morning, compelling production of accounts from the court, and at York on the same mission on Wednesday afternoon. Not comparable with Dick Turpin's efforts, for he had two nights sleep on the way, but good enough to let the court officers know his movements could not be anticipated. He fought for King James at The Battle of The Boyne, but was pardoned and allowed to return to England where he observed with sardonic amusement the efforts of some of King William's soldiers to be appointed as his replacement.

Sir Caesar who had been born in 1623 was only 14 when he inherited the baronetcy on the death of his father. He was at school in England at the time, and in England he remained and it was only during the last few years of his life that he returned to Tintern. At the age of 24 he married Frances, daughter of Sir Francis Clarke, a wealthy landowner who had estates at Thame and Hitchin as well as other land in Oxfordshire and Buckinghamshire though none of it came to Caesar by way of marriage settlement. At first the couple divided their time between London and Staffordshire attending to the remaining Colclough estates and living at the Delph House at Newcastle. Later they rented Greenham Manor in Berkshire from Lord Lucas and that continued to be their principal residence. Sir Caesar became involved in the local affairs of Berkshire for which he was Commissioner of Assessment and a J.P. He was a Burgess of Newcastle and in 1661 was elected to Parliament for the borough which he continued to represent until 1679. His claim to do this was, according to the Staffordshire Record Society, that he was fourth cousin of the Colcloughs of Blurton and Tunstall, was head of that family, then wealthy men of the middle class and burgess members for Newcastle, and that he was a Protestant. A report on the gentry of Staffordshire made in 1662 says "COLGHCLOUGH, Sir SEASOR: burgess of (Chesshire) (Newcastle) £600pr. Reported loyal and orthodox but a stranger. A sober man."

Twenty-five years later Lord Shaftesbury - Anthony Ashley Cooper of the CABAL - described him as a 'vile' man though Lord Wharton had considered him a friend to be managed by Sir Richard Onslow. He sat on some parliamentary committees, half-a-dozen in 27 years. He was no more assiduous in his attention to his parliamentary duties than to his duties as a Berkshire magistrate and in both spheres he is more often noted as absent than present. On one occasion he had to be fetched to the House forcibly in the custody of the Serjeant-at-Arms. He was one of the Commissioners for Recusants in 1675. He died in 1684 at Tintern where he had spent the last few years of his life.

His children spent most of their time in Berkshire or at the Colclough Hackney mansion which the family occupied during parliamentary session, but his daughter Margaret was in Ireland sufficiently frequently to get herself married at an early age to Robert Leigh of Rosegarland. On his father's death her brother, also Caesar, inherited the baronetcy and took over Tintern Abbey but he survived there only for three years. All that is recorded of him is that he became Deputy Lieutenant Governor of Kilkenny and that on his death the baronetcy which had been conferred on Adam and the heirs male of his body became extinct and that the Tintern estates passed under his will to his sister Margaret for life, subject to a condition that her husband adopted the name and arms of Colclough, with a gift over to her children or failing issue to their cousin Caesar of Duffry Hall. Leigh duly changed his name to Colclough and moved with his wife to Tintern where he died in 1694. A couple of years later Margaret married a widower, John Piggott, a barrister of Kilfinny, Limerick, and a member of the Piggott family of Sevoy Castle near Tintern. On moving to Tintern he too adopted the name and arms of Colclough by Royal licence but he did not survive Margaret and when she died in 1723 the estates passed under the will to Caesar of Duffry Hall, great grandson of her grand-uncle Dudley who had died in exile.

In 1692 Margaret Leigh Colclough sold the lands at Dunmain to Arron Lambert, who built a house there. In 1714, Lord Altham, Earl of Anglesea, moved there with his wife Mary Sheffield, daughter of the Duke of Buckinghamshire and Normandy, whom he had married in 1706. A child, James, was born at Dunmain in 1715, and the God parents were Anthony Colclough, Anthony Cliff and Mrs Piggott, all of Tintern. The child was put out to Joan Lundy, a wet nurse, whose father was a shepherd on the estate. In February 1717 the couple parted, Lady Altham going to live at Capt. Butlers in New Ross. The cause of the seperation was Thomas Palliser of Great Island, whose ear was partially severed at Dunmain by Lord Altham. In 1719 Lord Altham and his son moved to Dublin and took up residence with a Miss Gregory in Inchicore. She was jealous of the 5 year old James and he was put out to lodge in Ship Street. In 1727 Lord Altham died. His brother Richard took the title and arranged for the 12 year old boy to be kidnapped and sold as a slave in Delaware. James finally escaped in 1740 to the patronage of an Admiral Vernon. In 1743, in The Kings Court Dublin, he set about reclaiming his titles and land. James won, but his uncle appealed and the case dragged on till Jame's death in 1760. The story inspired Walter Scott's Guy Mannering and Smollett's Peregrine Pickle as well as Charles Reade's story The Wandering Heir.
