Proprietary Records is an artificial title which is ordinarily used to identify the earliest records of the colony. They are general record books covering all sorts of proceedings of the provincial government, especially records of the Provincial Court. These are the only source now extant for probate records for the period 1643 to 1657. This volume contains abstracts from Patent Record F & B (1640-1658); Patent Record Z & A (1637-1651); and Patent Record A & B (1650-1657).
