Both these cultures were forced ever westward and finally southward as each succeeding generation needed land. The migration moved through the Susquehanna River Valley, then southward down the Shenendoah Valley of Virginia into North and South Carolina. The Martins arriving prior to the Revolutionary War, the Kevers shortly after.
There Samuel Martin garnished a reputation as an Indian fighter and Revolutionary War Captain of Militia. All this while raising a family and building a profitable farm.
There also, Jacob Kever took as his bride an American Indian woman (probably Cherokee). The history of North Carolina tells how it was common practice for the Pennsylvania Dutch emigrates to marry with the Native Americans in the area. Photographs of the Kever family clearly show the Native American features. I assume Cherokee since it was the predominant tribe in the area.
