It was, of course, by way of the river that the settlers came to this region after the grant of the Colony of Maryland to Lord Baltimore as Lord Proprietor. This colony of Maryland differed from the other colonies in the fact that all the land was the property of Lord Baltimore, to give or sell as he pleased. Another difference was the establishment of the Manorial System, by which the owner of one thousand acres or more became Lord of his Manor. (It was almost like the Feudal System.)

In 1703 a grant of 795 acres was made to Ninian Beall, beginning thus:

"Charles, Absolute Lord and Proprietor of the Province of Maryland....

Know yee that for and in consideration that Ninian Beall of Prince Georges County had due unto him 795 acres of land within our Province....

Rev. James McVean (See Chapter XI)

We do therefore grant unto him the said Ninian Beall all that tract or parcell of land called Rock of Dunbarton, lying in the said County, beginning at the Southwest corner Tree, of a tract of land taken for Robert Mason standing by Potomack River side at the mouth of Rock Creek....

To have and to hold the same unto him the said Ninian Beall, his heirs and assignees forever to be holden of us and our heirs as of our manor of Calverton in free and Common Soccage by fealty only for all manner of services yielding and paying therefor yearly unto us and our heirs at our receipt at the City of St. Maries at the two most usual feasts in the year—at the feast of Annunciacion of the Blessed Virgin Mary and St. Michael the Archangell by even and equal porcions the rent of one pound eleven shillings and nine pence half penny sterling silver or gold....

Given under our Greater Seal of Armes, this eighteenth day of November, one thousand seven hundred and three, witness our trusty and well beloved Colonel Henry Darnell, keeper of our said Greater Seale in our said Province of Maryland."
