The second act passed in 1748 related to the erection of Frederick
County from all the less settled portions of Prince George's County.
According to this law it was enacted

" that all the land lying to the westward of a line beginning at the lower
side of the mouth of Rock Creek and thence by a straight line joining to the
east side of Seth Hyatts plantation, to the Patuxent River should be taken
from Prince George's County and made into a new jurisdiction to be called
Frederick County."

A portion of this line still forms the boundary between Montgomery and
Prince George's counties.

The final change in the boundaries of Prince George's County was
made in 1791 when the District of Columbia was ceded to the National
Government from portions of Montgomery and Prince George's counties.
