In the mid 17th century, around 1655-6, an Iroquoian group known as the Westo invaded Virginia. While many theories abound as to their origins, they appear to have been the last of the Eries and Chonnontons who invaded Ohio at the start of the Beaver Wars. The Westo seem to have pushed into southern West Virginia, then moved straight south to move on the smaller Siouan tribes of the Carolinas. In the 1680s, they were destroyed by a coalition of native warriors led by a tribe called the Sawanno. There is also a note from the Cherokee that a group of "Shawnee" were living among them in the 1660s (following the Westo invasion, but prior to their defeat), then migrated into southern West Virginia.
