Günyurdu, Nusaybin

Mār Bōbo (today called Günyurdu) was historically inhabited by adherents of the Church of the East.^[9] The Church of Mār Bōbo was constructed in either the 6th century or the 7th century.^[8] The church was likely adopted by Syriac Orthodox Christians in the 18th century.^[10] It has been suggested that the village's population may have converted to the Syriac Orthodox Church or the village was abandoned and resettled by Syriac Orthodox Christians.^[9] The monk Barṣawmō of Arbo is attested at Mār Bōbo in 1870.^[11] In the Syriac Orthodox patriarchal register of dues of 1870, it was recorded that the village had 32 households, who paid 143 dues, and did not have a priest.^[12]

The Syriac Catholic bishop Gabriel Tappouni recorded that Mār Bōbo was inhabited by 300 Syriacs in 50 families and was served by two priests in 1913.^[13] In 1914, there were 400 Syriacs, as per the list presented to the Paris Peace Conference by the Assyro-Chaldean delegation.^[14] They adhered to the Syriac Orthodox Church.^[15] It was owned by Sarohan, chief of a subsection of the Haverkan tribe.^[16] Amidst the Sayfo, Syriac refugees from the village of Tel-Aryawon were granted refuge at Mār Bōbo by Sarohan, who subsequently escorted the Syriacs from both villages to Beth-Debe, where they survived the genocide.^[17]

There were 410 Turoyo-speaking Christians in 57 families at Mār Bōbo in 1966.^[2] The Church of Mar Aho was built in 1975, incorporating the Church of Mar Bobo.^[10] The village had a school by 1981.^[18] In 1995, the village's population of 150 families was forcibly evicted by the Turkish Armed Forces as part of the Kurdish–Turkish conflict and many emigrated abroad to Germany or Switzerland.^[19] Mār Bōbo lay abandoned until it was resettled and rebuilt by eight returning Syriac families in 2003.^[5][19]
