The Society is composed of men and women who are descended in their own right, direct and legitimate, from the First Baron of Baltimore or from one or more of the Colonists who were granted by the Lord Proprietor of the Province of Maryland a manor in fee simple with manorial rights and privileges or from his or her heir at law.
For purpose of membership, a manor is defined as a tract of land of not less than 1000 acres granted by patent to a Maryland Colonist prior to the year 1722. The grant must have invested the patentee with all manorial rights and customs of Feudal England including the privileges of Court Leet and Court Baron. The title of Lord of the Manor must have descended in primogeniture as fixed by the laws of Ancient England.
Membership is by invitation only.
