His nation was that of the Jalofs; his tribe, or cast, the Pholey, or Foulah; and his native place Bunda, a city of Galumbo, in the kingdom of Futa, in Central Africa, opposite Tombuto.

Ibrahim, the grandfather of Job, was the founder of the city of Bunda, during the reign of Abubeker, then king of Futa; who gave him the proprietorship and government of it, with the title of Alfa or High Priest.

In the month of February, 1730, the father of Job, having learnt that an English vessel had arrived in the Gambia, sent his son thither, attended by two domestics, to procure some European commodities; but charged him not to cross the river, because the inhabitants of the opposite bank were Mandingoes, enemies of the kingdom of Futa.
