Abraham is a former slave to Daniel Collins.
Abraham was chained up in a barn of Daniel Collins' plantation as his slave, when he met Jefferson Jackson. Abraham commented on the irony of Jax being named after two famous slave owners. He and his fellow slaves were soon rescued by Amaya Jiwe, who helped to convince Mary and the rest of them to escape, rather than stay. Allowing the others to escape, Abraham aided Jefferson to steal the Confederates' battle plans from a hidden location in the Collins Plantation. The group then traveled to Ulysses S. Grant's camp, where they were welcomed with open arms.
