In 1691
Lower Norfolk County was in turn divided in two to form Norfolk and
Princess Anne counties to accommodate settlement. Captain
Adam Thoroughgood (1604–1640) is credited with naming Norfolk County. Thoroughgood was a prominent resident of the colony. Like so many others at that time, he had been born in England and immigrated to Virginia. He named the new county after his original "home" county across the Atlantic Ocean. After 1691, Norfolk County remained more or less intact for over 200 years.
Portsmouth became the
county seat and a major area of commerce, along with
Norfolk. Smaller towns were formed at
Berkley and
South Norfolk. In 1871, Portsmouth and Norfolk became independent cities, a jurisdiction in Virginia, and separated from Norfolk County, though Portsmouth remained the county seat. South Norfolk became an independent city in 1919. In the following years, the county lost additional territory. The
incorporated town of
Berkley as well as the areas of
Sewell's Point,
Willoughby Spit, and
Ocean View were annexed successively by Norfolk. By 1960, the entire area of Norfolk County on the east side of the
Elizabeth River north of Virginia Beach Boulevard had been annexed by other jurisdictions. On other sides, West Norfolk (Churchland) was lost to Portsmouth, and South Norfolk had also annexed a portion of the county. == 1963: Creating a new city, Chesapeake ==
