In all the world, 鲁瑟 (Reuther 
, Ruscher , 鲁瑟 
) is a very rare principally masculine, but very seldom feminine forename. The first name 鲁瑟 is characteristic of Latin America and the Caribbean, particularly Brazil, where it is a very rare male name. Much more prevalently, 鲁瑟 is the last name as well as the forename.
