The Provincial Land Office of Maryland was responsible for the dispensing of land from 1634 to 1777. Maryland Proprietor's Rent Rolls and Debt Books were the means by which he kept track of the yearly rents he was entitled to. The Debt Books, in particular, consist of a list of persons owning land with the names and rents of each tract that he or she owned. The surviving Debt Books are arranged by county, by year, and then by the name of the person paying the rent. Distinguished Maryland genealogist Vernon. L. Skinner has painstakingly abstracted the contents of all extant Debt Books, county by county. This is the fourth of five volumes pertaining to Baltimore County.
