In the Ottoman Empire, Syriac communities kept their own baptismal books, marriage, funeral and other records, but not all these have survived. However, many Syriac records can still be found in various libraries, churches, monasteries in the West and East, especially in Mardin, which was once the headquarters of the Syriac nation and their patriarchate. The Syriac Garšūnī manuscript found in the Church of the Forty Martyrs in Mardin (number 1006, dated 1872) contains several lists of different subjects that go back to the late period of the Ottoman Empire. These lists, published here for the first time with annotations, are an important historical source not only for Syriac communities, but also for the social, economic, cultural and religious history of places in the Near East, during the 19th century.
