Sussex County, Delaware
There is no known history of courthouse disasters in this county.
- Parent County: Sussex County was created 8 August 1673 from Deale (old) County.
- County Seat:Georgetown 
- Because of the ongoing boundary disputes between Lord Baltimore of Maryland and William Pitt of Pennsylvania, much of Sussex County (excepting a few miles inland from the coast) was also recognized as part of Maryland's Somerset County up through 1760. Both Pennsylvania (and, after 1710, Delaware) and Maryland issued land patents for the area, sometimes in conflict with each other.
The British Crown ordered the dispute to be settled in 1760, and commissioned Charles Mason and Jermiah Dixon to survey the boundary. In 1769, the survey was completed, defining the border between Maryland, Delaware and Pennsylvania that exists today.
The border between Sussex and Kent Counties, Delaware was set in 1683 and has not changed since then.
