An early settler of this region was James Ewing, who arrived in 1770 and built a grist mill on Robinson's Run. Gabriel Walker and Isaac Walker, Scots-Irish brothers from Lancaster County, Pennsylvania, arrived in 1772. Gabriel Walker's household was raided by Indians in 1782. Walker's Mills, the village east of Rennerdale, is named for Isaac Walker. Between 1760 and 1790, Gabriel Walker built a log cabin about northwest of present-day Rennerdale; today known as the Walker-Ewing Log House, the structure still stands. In 1976, it was placed on the National Register of Historic Places. Many Walkers have continued to live in the area up to the present day.
