On January 10, 1914, four sisters were sent to Endjé, later called Zarevbrod. In the German emigrants community they were to take over school teaching, pastoral care and service to the sick. In 1948 all but two German sisters left the Communist Peoples’ Republic to return to Germany after their work had become more and more limited. The other two remained with the Bulgarian sisters. They lived and worked in a home for mentally challenged people.

In 1990, after the end of the communist regime, the sisters won back their freedom and new missionaries joined the brave community once again. They devote themselves mainly to the predominantly poor population..
