The great value of the Provincial Land Office Debt Books is that they enable the genealogist to track land ownership over various years in cases of intestate estates, land inherited by women, and land that is not specified in a will. They are now the basis of a series of record abstracts from Vernon L. Skinner, Jr. This volume is the first in a series covering Calvert County, Maryland, an original county formed in 1654. The information in this series is presented in a tabular form as follows: liber and folio citation, with any pertinent date; name of the person paying the taxes; name of the tract of land and amount of acreage.
