He was born in London, England and in 1861 married Maria Frederica Davies, a niece of the great statesman, George Canning.[3] Having taken a prominent part in the agitation for the separation of Northern Queensland from the rest of the colony, and its formation into a distinct colony, he was in 1887 commissioned to go to England with Mr. Lissner to press the matter upon the attention of the Home Government, Harold Finch-Hatton and Dr. Ahearne having done much to bring the matter into the region of practical politics by their exertions during the previous year.[2] Though not successful in inducing Lord Knutsford to take steps for the separation of Northern Queensland, the advanced phase which the question has since assumed is a good deal due to the efforts of the delegation of 1887.In June 1888, on the formation of the second Thomas McIlwraith Administration, Black became Secretary of Public Works, and continued to hold the post when five months later the Ministry was reconstructed under Boyd Dunlop Morehead.[1] Then Black decided to try his luck on the Coolgardie, Western Australia goldfields with some of his family; he arrived in 1896 and set up as an attorney for mining companies.
