John was the only surviving son and inherited Dolaucothy, he became a Judge on the Welsh Circuit.
John Johnes was educated at Oxford and in due course called to the Bar. He was a good businessman and soon had put the whole estate on a sound financial basis. In 1822 he married Elizabeth Edwardes, daughter and heiress of the Reverent John Edwardes (1765'961847) of Gileston Manor in Glamorganshire, a younger branch of the family of Edwardes, of Rhyd-y-gors. They had two daughters, Charlotte Anne Maria (1825 - 1911) and Elizabeth (1834 - 1927). Judge Johnes became a widower when his wife Elizabeth died on the 25 June 1848.
Charlotte married Captain Charles Caesar Cookman Esq, the eldest son of Edward Rogers Cookman, Esq. of Monart House, County of Wexford. Charles Cookman died on 4 June 1859 leaving Charlotte a widow.
In the summer of 1876, Dolaucothi made national news when Judge John Johnes was murdered in his study on 19 August by Henry Tremble, his Irish butler of 17 years service, who killed him with his master's shotgun. Tremble also severely wounded Charlotte Cookman. Tremble was very upset that Judge Johnes had refused his application for the tenancy of the Dolaucothi Arms, a local public house, which he had previously promised to him. Johnes' reasons for not considering Henry Tremble for the position involved Trembles' wife's disposition for drinking excessively.
Tremble then headed into the village of Caio with the intention of murdering John Davies, the inn keeper he felt had deprived him of the position he sought. Davies was away in Carmarthen that day, so after threatening a local police constable he retired to his own house 'Myrtle Cottage' and shot himself.
Henry Tremble, 36, entered service at Dolaucothi upon the death of Captain Cookman in 1859. Tremble had been Captain Cookman's valet in Ireland and he had accompanied him to Wales upon his marriage to Charlotte. At Dolaucothi he worked his way up to the role of butler but was known to possess a somewhat violent disposition. John Johnes would have dismissed him on several occasions previously, but was dissuaded from doing so by Charlotte, who felt that this would betray the memory of her late husband who had commended the care of his favourite servant to her.
On the 26 August 1876 Judge Johnes' remains were interred in the family vault at Caio Church, when Canon Phillips, subsequently Dean of St. David's, and Charles Chidlow, vicar, officiated. Charlotte resumed the name of Johnes under her father's will of 1876 and lived out her days at Dolaucothi, co-inherited with her sister Elizabeth.
John married Elizabeth EDWARDS  [MRIN: 9815], daughter of Rev John EDWARDES of Gileston Manor GLA  and Unknown, on 8 Oct 1822.
