I have traced the line of Peter Dicks and Esther Maddock back to the Chester England area....through three generations of "Roger" Dicks back to around 1550. I suspect this is as far back as I can go, based on existing records.
For many, many generations the Dicks were Quakers and Peter settled on land near Chester PA purchased in England from Wiliam Penn. His brother James (James was not his father as some think)was a "first purchaser" of Penn property. He sold that to Peter, because the Dicks and Maddock family decided that Peter and Esther would be better off away from the Maddock family in England!
