For Riemann there are 475 on Yasni with different names.
Among the most common last names on Yasni Riemann is on position 4052.
During the last seven days Riemann was searched 4 times.
To my knowledge, the name comes from the Riemann rope and belt people for the ship's rigging. Why he in the north (coast) more common than in Germany.
