In 1702 Bridget Domvile, Sir Thomas's (1650-1721) only daughter, married Henry Barry, third Lord Barry of Santry. He died in 1731; Lady Barry survived him. Their only son Henry was born in 1710. His teenage misconduct incurred criticism from no less than Jonathan Swift, in a confrontation with Lady Barry that became the talk of the town, and severed the friendship between them. A few years later young Henry brought the ultimate disgrace upon the family name.
In 1739 he was tried for the murder of one of his servants, and sentenced to be beheaded. 'Lord Barry had been drinking for some hours in a chamber in (a public-house in Palmerstown), where he had an angry dispute with one Humphreys, during which he endeavoured twice to draw his sword, but, failing to do so, he suddenly left the room, and meeting (the) deceased in the passage pushed him with his right hand; he went towards the kitchen, whither he was followed by Lord Barry, who swore he would kill any man that should speak a word. The poor man spoke and Lord Barry stabbed him with his sword...' (Benjamin Adams' 'History of the Parish of Santry' 1884)
Lord Barry was tried by his fellow peers and found guilty, but with an unanimous recommendation to mercy. He was sentenced to be beheaded, but His Majesty King George II, on the mediation of the Duke of Devonshire, then Lord Lieutenant of Ireland, and other noblemen, granted Barry pardon for his crime.
Another account ('History of Tallaght' by William Domville Hancock, 1877) says that Lord Barry would have been executed but for the intervention of his uncle, Sir Compton Domville, then living at Templeogue. The city water-course ran through Sir Compton's grounds, and he declared that he would cut off the supply of water to Dublin if the sentence was carried out...
Lord Barry's title was 'attainted' from 1739. He retired to Nottingham after the trial. His first wife, Anne, died there in 1742. He married again Elizabeth Shore of Derby, a member of the Teignmouth family, a short time before his death without children on 18 March 1751. There were plans to take him back to Dublin for burial, but instead he was interred at St Nicholas's, Nottingham. The Parish Register notes: ‘Burial 22 March 1751, the Hon Henry Barry, Esq, formerly Lord Santry of the Kingdom of Ireland...’
(In the Nottingham area there are records of, for instance, Ann Dummile, daughter of George and Ann, baptised at Sutton Bonnington, 6 May 1729; also Tomas Domvill, witness to an apprenticeship indenture, in St Nicholas' parish, Nottingham, 14 June 1686; etc. Did Barry go to Nottingham because relatives of his mother's lived there?)
In his will Barry left his estates to his uncle Sir Compton Domvile, Bart., of Templeogue, County of Dublin, Clerk of the Crown and Hanaper, and Privy Councillor. Sir Compton represented the county of Dublin in Parliament for 44 years and died without children in 1768, when the Baronetcy (created 1686) expired. He left Santry (qv) and Templeogue to his nephew, Charles Pocklington Esq, son of Elizabeth Pocklington (nee Domvile). In accord with his uncle's will Charles Pocklington assumed the surname of Domvile. He was MP for the county of Dublin 1767-1769, and had four sons and seven daughters.
Loughlinstown went to the Rev Benjamin Barrington, who was also obliged to take the name of Domvile, but later died without issue.
