HE occasion of this volume is substantially, per haps sufficiently, stated in the opening of the first chapter. To the explanation there given a few particulars may be added. There has always been, the author believes, a strong and very reasonable interest in the personality of William Penn, as the Founder of Penn sylvania, and as a worthy figure in the world's history, and some of this interest attaches to the line of those who have descended from him. The volume here prepared assumes simply to deal with this Family subject. It is not a history nor a biography. In one or two places, perhaps, the record has been permitted an extension which could not be entirely justified by the plan of the work, but excusing this by the special interest of the subject at those points, the author thinks the book has been fairly confined to its original and legitimate plan.
