Description
Mercer County has the most complex boundary formation history among New Jersey's counties, and researchers of slavery in this area are encouraged to consult archival records related to the four surrounding counties which gave their territory to form Mercer in 1838. Mercer County was created by annexing Trenton, Princeton, and their surrounding areas from four separate counties that intersected in the vicinity of Assumpink Creek. Sections were taken from Hunterdon County (where Trenton was originally located), Somerset and Middlesex Counties (area surrounding Princeton), as well as Burlington County (area south of Trenton along the Delaware River).

See Hunterdon, Somerset, Middlesex, and Burlington for more complete information about demographics and slavery in the area.

Historically, the community of Mill Hill was considered the county seat of Mercer County. Mill Hill has been annexed by Trenton and is now a neighborhood in the city.
