Dunlo married in 1889 and succeeded his father as the 5th Earl of Clancarty in 1891. The period between those events saw his father, who strongly objected to the marriage, try to undermine it, and place as much as possible of the family estate beyond Dunlo as heir. His initial step was to order Dunlo, who was still under the
age of majority of 21, to travel to Australia. A petition for divorce was argued in court in 1890, on behalf of Dunlo, before
Sir James Hannen. It was based on an affidavit signed in Australia by Dunlo, who later claimed he had signed it without understanding its implications, and named Isidor(e) Emanuel Wertheimer in alleged adultery with his wife
Belle Bilton, now Lady Dunlo, in London. The jury found that no misconduct of Lady Dunlo with Wertheimer had been proved; and she was given a highly-paid role in a burlesque
Venus by the impresario
Augustus Harris. ==Later life==
