Sophia Dunn, the daughter of Jeremiah Dunn, was born circa 1762, most likely in Frederick County, Virginia. About the year 1787 she moved with her parents and family to northern Kentucky. A few months later, while living in Fayette county, Kentucky, Sophia married William Harrison. He was born circa 1758 in Virginia, possibly the son or kin of William and Hannah Harrison. After their marriage William and Sophia lived for a time in Fayette County, Where William owned land on Grays Run and Flatt Run, tributaries that emptied into the South Fork of Licking River. When Harrison County was created in 1793, William and Sophia became a part of that county. during the year 1799, William purchased two lots in the town of Cynthiana, the county seat of Harrison County and the town founded by his kin Robert Harrison.
Soon after the turn of the century, William and Sophia left Harrison County and followed Robert and James Harrison northward into Ohio. They settled for a time near Paint Creek. About 1818, William and Sophia, together with Robert and James Harrison and their families, moved west to Sullivan County, Indiana, where they farmed. Three years later in 1821, the area where they lived became a part of Stafford Township (later Washington Township) in Greene County, Indiana. About 1826, William and his family, and the family of James Harrison moved north up the Wabash River to Warren County, Indiana, where they were listed on the 1830 census. William died 30 September 1832 at age seventy-four, and Sophia died 22 December 1835 at age sixty-five.
