First found in Silesia, where the name emerged in mediaeval times as one of the notable families of the region. From the 13th century the surname was identified with the great social and economic evolution which made this territory a landmark contributor to the development of the nation. The Origins of the name make it likely that several branches of the family emerged independently during the Middle Ages; there are records dating from the 13th documenting the presence of the name Roser in Schleswig-Holstein, Pomerania, Alsace, Swabia, and Bohemia, as well as Silesia.

Some of the first settlers of this family name or some of its variants were: Thormut Rose, who sailed to New England in 1651; Peter and Johanna Rose, who sailed to New York in 1708; Peter Rodolf Rose, who came to Georgia in 1734.
