Dinnur, also spelled Dhinnur, is a hamlet located three kilometers north from its major village of Thally Kothanur in Tamil Nadu, India.[4] It is eight kilometers away from the town of Thally. The primary occupations of the villagers are farming and labor service. This village comes under the Kuppatti Gram Panchayath.[5]
Dinnur holds a unique cultural identity, heavily influenced by the presence of Catholic missionaries who settled in the nearest village Dasarapalli over a century ago. As a result, the village has a notable population of Catholics who actively participate in religious rituals and festivities.[6]
