This volume is derived from this important source for Maryland genealogists. In compiling the series, Mr. Skinner has worked primarily from microfilm copies of the Prerogative Court records; however, when necessary to resolve problems of paleography, he has consulted the original manuscripts, located at the Maryland State Archives in Annapolis. In all, the latest book in this distinguished series refers to an additional 7,000 colonial inhabitants of the Province of Maryland. For the most part, the transcriptions state the names of the principals (testators, heirs, guardians, witnesses, administrators, and so forth), as well as details of bequests, names of slaves, appraisers, and more.
