Charlestown Township  and the stream of water which flows through it were named in honor of Charles Pickering, of Asmore, in the county of Chester, England, his first name--Charles--being given to the township, and his surname--Pickering--to the creek.  Charles Pickering was an Englishman who, it is said, crossed the ocean with William Penn, and wandered up the Schuylkill River in search of treasure.  Supposing that he had discovered traces of silver on the banks of the stream which now bears his name, and believing that the neighboring hills contained large quantities of the precious metal, he returned to Philadelphia, and obtained from Penn a grant of a large tract of land bordering upon the stream.  He subsequently dug up and sent to England a large quantity of the supposed precious metal for analysis.  What the result was is not known, but it is supposed it was unfavorable, as the efforts at mining were abandoned.  Traces of the excavations made in these mining operations are said to be still visible.
