Lt. a conversation with a researcher with the name originates from the Middle Ages Rosenberger and meant that there was in the village or the city many roses (but wild roses). These roses were distributed in these villages so often that the inhabitants of all the Rosenbergs were called. The name comes from there Rosenberg 2. Possibility. Up on the hill in the monastery, the monks made the rosaries ago for the population. Hence the name "The Rose or The Make Rosenberger"
