Yellow Hill in Adams County's Butler Township was once the home of several African American families from the 1840s through the 1890s. The settlement was founded by Edward Mathews, who owned 16 acres of land and raised a large family. Yellow Hill was once called Pine Hill. Some believe that the name reflects the skin tones of those who once lived there. Mathews was reputed to be an Underground Railroad agent working with nearby Quaker farmers. Three of Mathews' sons left Yellow Hill to serve in the United States Colored Troops. Mathews gave land for a church and cemetery where three veterans of the USCT were once buried (one of them was his son William). Edward Mathews' granddaughter Jessie Ellen Mathews Vann, the orphan of a USCT veteran, endured a difficult childhood but used her education and tact to become a respected businesswoman, American diplomat and nationally-recognized community servant. She was often a guest at the Eisenhower's Gettysburg farm and was appointed by President Eisenhower to serve on several committees.
