These are maps of various pieces of property in the Southwark division of Philadelphia which belonged to certain members of the Shippen family. They include maps taken, in part, from Philadelphia City records, as well as up-to-the-minute surveys done when the property was sold or subdivided. There are names of purchasers in some cases, showing which lots were acquired. There are also drawings of tracts of lands near roads or water and of estates of persons other than the Shippens.
