Jordanes, the historian of the Goths, reported ("Getica" 280) that after the Battle of Bolia, the Ostrogoths attacked the Suevi (ruled by a man named Hunimund, who also seemingly led an attack on Passau) by crossing the Danube when it was frozen and going into a high Alpine area held by the confederates of the Suevi at the time, the Alamanni. (He said that several streams start in the area and enter the Danube.) The region held by those Suevi was described as having Bavarians to the east, Franks to the west, Burgundians to the south, and Thuringians to the north. The text seems to indicate that the Suevi had moved into the Alamannic area but that Suevi were seen as distinct from both Alamanni and Bavarians. Thay was also the first mention of Bavarians, who are also often proposed to have had Marcomanni in their ancestry.
