They had two children, Fiqtor and Theodora.
During Ahmad ibn Ibrahim al-Ghazi's invasion of Ethiopia, Menas had been captured but treated well as a valuable prisoner.
Although the fate of prisoners of war at the time was to be castrated and enslaved.
This clemency came to an end in 1542, when the Imam, desperate for help from his fellow Muslims, included Menas in an assortment of extravagant gifts to the sultan of Yemen in return for military aid.
However, Imam Ahmad's son was later captured in the aftermath of the Battle of Wayna Daga, Gelawdewos used his prisoner to recover his brother Menas; according to Pankhurst, "when the royal family was reunited there were many days of celebrations."
