Delaware (State of)
Originally the "lower counties" of Pennsylvania, and thus one of three Quaker colonies founded by William Penn, Delaware has developed its own set of traditions and history.
Charter of Pennsylvania, from Charles II to William Penn
William Penn suggested what he wanted, and the Royal bureaucracy suggested suitable modifications of the gift. The resulting charter is a shrewd and fair legal document, but contained a major geographical error.
Chester County, Pennsylvania
Chester was an original county of Pennsylvania, one of the largest until Dauphin, Lancaster and Delaware counties were split off. Because the boundaries mainly did not follow rivers or other natural dividers, translating verbal boundaries into actual lines was highly contentious.
