It is a figurative statement. The ancestors of a certain family unit in Africa (Arochukwu, to be precise) raised the dust through the worship of the most popular heathen deity in Igbo land, Ibinu Ukpabi (or Long Juju), and through the organization of the Aro Confederacy, an organized mafia cult under the auspices of Long Juju, through which slave trade flourished. But Uzo Ogbonna, a Christian convert, was determined to see to the destruction of the Long Juju shrine and its cult of human sacrifice, of which his father, Mazi Ogbonna, was a staunch member. Little did Uxo know that the British authorities would soon launch an insurgency campaign towards the destruction of the shrine. This led to the Anglo-Aro War (1900-1901) which was fought between British soldiers and the Eze-Aro's warriors. The British, with their sophisticated arsenal, won the war, after which Mazi Ogbonna and other notorious Long Juju cultists were brought to face a tribunal and was later sentenced to death by hanging.
But before the war, Uzo had already escaped the tyranny of his polygamous father by eloping to the colonial town of Calabar with Ivuaku, his hearttrob, another Anglophile. It was in the port of Calabar that he met Mary-Ann, a British missionary with whom he made friends. But under some circumstances described in the 600-page novel, Ivuaku died, followed by Uzo much later. However, Uzo's now orphaned triplets must be taken care of by Mary-Ann whose illness necessitated her sailing back to England. It was in England that Mary-Ann died, leaving the helpless triplets with whom she sailed to England in the hands of their destinies . . .
The Book Two and Book Three of this captivating family saga, set in Nigeria, the United Kingdom and North America, narrate how the triplets were separated within the ambit of the British Adoption Act, making it seemingly impossible for them to get back together again, and how they reunited 79 years after by way of the activities of their children and grandchildren . . . It is a saga that traverses up to four (4) generations, counting from Uzo Ogbonna. Why don't you get a copy to find out what made it possible for three babies--the first taken to Belfast, the second taken to Nottingham, and the third taken to Brooklyn, NY--to reunite after 79 years. This is the climax of the saga.
The reunion of the triplets, their children, their grandchildren, and their great-grandchildren, brought about the settling of the dust raised by their ancestors in far-away Arochukwu . . .
