Sussex County was created on 1670 and was formed from Sussex County. The County was named for the English county of Sussex, which was his home county.. The County Seat is Georgetown.
Delaware's southernmost county. This was originally part of the Hoornkill district court, set up by the Dutch Governor Colve in 1673. Hoornkill was divided into Saint Jones and Deal Counties in 1680, and in 1682, Deal County was changed to Sussex County for William Penn’s own county in England. Sussex County Delaware was claimed for a number of years by both Maryland and Pennsylvania. Delaware was initially settled by the Dutch and Swedes, but when the Duke of York took New York from the Dutch, his agent captured Delaware in 1664. In 1682, Delaware was granted to William Penn along with Pennsylvania. Lord Baltimore disputed Penn's ownership of the three Delaware counties, and the southern and western areas of Sussex County were claimed by both Maryland and Pennsylvania, but were governed by Maryland until the Mason-Dixon Line was approved by George III in 1769; when all of Delaware was awarded to Pennsylvania. In 1769, Kent, Sussex , and Sussex counties met in Constitutional Convention and the State of Delaware was formed.
