Dauphin County was formed from part of Lancaster County by an act of the Pennsylvania General Assembly of 4 March 1785, and named in honor of the oldest son of the King of France for his assistance during The Revolutionary War. That Act also provided that its seat of government and justice should be "near Harris's Ferry." The city that formed there was initially called Louisbourg in honor of the French King Louis but, in 1791, was named Harrisburg in honor of John Harris.

The Dauphin County area was originally part of Chester County which, by an Act of The Pennsylvania Assembly in 1729, became part of the newly formed Lancaster County. John Harris of Yorkshire England, who arrived in Philadelphia with William Penn, eventually settled on the Susquehanna River and it was his son John Harris, Jr who, in 1782, petitioned The Pennsylvania General Assembly to establish what became Dauphin County and for which Harrisburg was eventually named.
John Harris, Jr, born c. 1727, was granted 300 acres of land December 17, 1733 by patent in the area now the site of The Dauphin County Court House. He farmed, developed a large trading business with Indians , and managed the ferry his father established on The Susquehanna River, eventually known as Harris’ Ferry. That ferry was used during The Revolutionary War to transport supplies.
