Volume IV in this series consists of abstracts of Prerogative Court of Maryland records for the period 1677 to 1682, as well as some inventories for 1702 to 1704. (Beginning in 1674, inventories and accounts were recorded in a separate series.) Mr. Skinner has combed through administration, bond, will, inventory, administration account, and final balance entries to produce this collection. The abstracts are arranged in chronological order by court session. In every instance, they give the names of the principals (testators, heirs, witnesses, administrators, and so forth). In many cases, we also learn the details of bequests, names of slaves, appraisers, and more. In all, what we have here are probate references to over 6,500 17th-century Marylanders whose existence and activities would otherwise remain hidden in some rich but very obscure records.
