The following comes from PLACES from the PAST: The Tradition of Gardez Bien in Montgomery County, Maryland by Clare Lise Kelly (M-NCPPC):
Though local tobacco plantations were small in scale compared to the large estates of the Deep South, they relied nonetheless on labor of enslaved people. In 1790, enslaved people were one-third the entire population in Montgomery County. The number of slaves exceeded that in Frederick County to the north (12%), but was not as large as its southern neighbor, Prince George’s County (52%). There were five times more slaves than free Blacks here in the 1840s-50s. The travesty of one person owning another and brutal treatment of enslaved people were realities of the county’s first 150 years.
