Al-Tahir Agha was a Turkish ruler sent to govern a province of Sudan, Al-Getaina, which was in the Ottoman Empire's domain, in the late 18th century. During his time in Sudan he married Khadeeja, the daughter of Mek Adlan II, the sultan of Sennar. Their union resulted in the birth of Hawa. Hawa married Mohammed Mulla, who is said to be a relation of Tahir Agha, who was a ruler of the Fur region of Sudan.
