Villages Trpinja, Bobota and Vera share common legend about origin of their names. According to legend ancestors of today's inhabitants of villages who settled in Great Serb Migrations under Arsenije III Čarnojević were called Bobe. They were fleeing from Ottoman Empire conquest to preserve their faith. Therefore, was formed local phrase which says Bobe suffer for faith or in Serbian Bobe trpiše za veru. From word Bobe was created name Bobota, from word suffer (Serbian:trpiti) was created name Trpinja and from word faith (Serbian:vera) was created name of village Vera.
