Kent County, Delaware in the context of "Caroline County, Maryland"

Delaware (/ˈdɛləwɛər/ DEL-ə-wair) is a state in the Mid-Atlantic and South Atlantic regions of the United States. It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.

Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the second-smallest and sixth-least populous state, but also the sixth-most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the second-most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County. The southern two counties, Kent and Sussex, have historically been predominantly agrarian economies. New Castle is more urbanized and is considered part of the Philadelphia metropolitan area. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic, Northeastern, and Southern regions of the country.

Dover (/ˈdoʊvər/ DOH-vər) is the capital and the second-most populous city of the U.S. state of Delaware, after Wilmington. It is also the county seat of Kent County and the principal city of the Dover metropolitan statistical area, which encompasses all of Kent County and is part of the Philadelphia–Wilmington–Camden, PA–NJ–DE–MD, combined statistical area. It is located on the St. Jones River in the Delaware River coastal plain. It was named by William Penn for Dover in Kent, England (for which Kent County is named). As of 2020, its population was 39,403.

The U.S. state of Delaware is divided into three counties, the fewest of any state in the United States: New Castle, Kent and Sussex. The origin of the county boundaries goes back to their former court districts.

New Castle County is the northernmost of the three counties of the U.S. state of Delaware (New Castle, Kent, and Sussex). As of the 2020 census, the population was 570,719, making it the most populous county in Delaware, with nearly 60% of the state's population of 989,948. The county seat is Wilmington, which is also the state's most populous city. New Castle County is included in the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD Metropolitan Statistical Area. The county is named after William Cavendish, 1st Duke of Newcastle (c. 1593–1676). New Castle County has the highest population and population density of any Delaware county, and it is the smallest county in the state by area. It has more people than the other two counties, Kent and Sussex, combined. It is also the most economically developed of the three.

Sussex County is a county in the southern part of the U.S. state of Delaware, on the Delmarva Peninsula. As of the 2020 census, the population was 237,378, making it the state's second most populated county behind New Castle and ahead of Kent. The county seat is Georgetown.

The first European settlement in the state of Delaware was founded by the Dutch in 1631 near the present-day town of Lewes on the Atlantic Coast. However, Sussex County was not organized until 1683 under English colonial rule.

The Chester River is a major tributary of the Chesapeake Bay on the Delmarva Peninsula. It is about 43 miles (69 km) long, and its watershed encompasses 368 sq mi (950 km), which includes 295 sq mi (760 km) of land. Thus the total watershed area is 20% water. It forms the border between Kent County and Queen Anne's County, Maryland, with its headwaters extending into New Castle County and Kent County, Delaware. Chestertown, the seat of Maryland's Kent County, is located on its north shore. It is located south of the Sassafras River and north of Eastern Bay, and is connected with Eastern Bay through Kent Narrows.

The Chester River begins at Millington, Maryland, where Cypress Branch and Andover Branch join together. It ends at the Chesapeake Bay in a very wide mouth between Love Point on Kent Island, and Swan Point, near Gratitude, Maryland. Cypress Branch rises in southwestern New Castle County, Delaware, and Andover Branch, with its tributary, Sewell Branch, rises in northwestern Kent County, Delaware. Millington is the head of navigation. Sewell Branch and Andover Branch join in a private impoundage of approximately 30 acres (120,000 m) about two miles (3 km) above joining with Cypress Branch and then becoming the Chester River.
