The last of these metropolitan bishops to reside at Mātā d-Mār Zayʿā was Mār Zayʿā Sargīs, who was consecrated at 11 years of age. During the Assyrian Genocide the bishop moved to the Salamas district between 1915 and 1918, then remained at the Baqubah refugee camp between 1918 and 1920, before moving to Mosul in 1920. From 1921 onward his see was fixed at the village of Khirshéniyah, immediately to the northwest of Alqosh in the Dohuk Governorate, where a small church was built dedicated to St. Zayʿā. Then in 1941 his see was moved to Baghdad, where a large Jīlū émigré community existed at Camp al-Sikak (the "Railroads Camp") with a mud-brick church dedicated to St. Zayʿā built in the 1920s.
