Earlier marriages, usually from the 1770s to 1919, are either with the clerk of the circuit court where the license was issued or at the Maryland State Archives.
Some records are at both locations.
A 1776 census was taken to determine revolutionary population and is indexed at the Maryland State Archives, but it is not available for all counties. Both versions of the published 1778 census contain transcription errors. A police census taken in Baltimore in 1868 is also located in the Baltimore City Archives. Prior to 1683, land was granted to those who transported settlers to the colony. A separate index covers private and proprietary manors as found in the patent records.
