Five years later, in 1634, the King had the colony reorganized under a system of 8 shires, with much of the Hampton Roads region becoming part of Elizabeth City Shire. In 1636, Thoroughgood was granted a large land holding along the Lynnhaven River for having persuaded 105 people to settle in the colony. Thoroughgood is also credited with suggesting the name of Norfolk, in honor of his birthplace. New Norfolk County was created when the South Hampton Roads portion of Elizabeth City Shire was partitioned off in that same year. Also during this reorganization, King James granted a further to Willoughby. This land would become the city of Norfolk in future. Shortly thereafter, in 1637, New Norfolk County was itself split into two counties, Upper Norfolk County and Lower Norfolk County. The modern city of Norfolk is located in Lower Norfolk. In 1649 the English couple William and Susannah Moseley migrated with their family to Lower Norfolk County. On the Eastern Branch Elizabeth River from Norfolk, they built a manor house with Dutch-style gambrel roof which later became known as Rolleston Hall. Rolleston Hall stood more than 200 years, until it burned down in the late 19th century. In 1670, a royal decree directed the "building of storehouses to receive imported merchandise ... and tobacco for export" for each of the colony's 20 counties. This marked the beginning of Norfolk's importance as a port city, due to its natural deepwater channels. Soon after 1673, the "Half Moone" fort at the site of what is now Town Pointe Park. This fort was constructed due to feared attack by the Dutch, but this threat did not materialize. Norfolk quickly grew in size, and by 1682 a charter for the establishment of the "Towne of Lower Norfolk County" had been issued by Parliament. Norfolk was one of only three cities in the Virginia Colony to receive a royal charter, the other two being Jamestown and Williamsburg. The town initially encompassed a land area northeast of the point of the confluence of the Eastern and Southern Branches of the Elizabeth River (today the point is in downtown). In 1691, a final county subdivision took place when Lower Norfolk County was split to form Norfolk County (present day Norfolk, Chesapeake, and parts of Portsmouth) and Princess Anne County (present day Virginia Beach). Norfolk was incorporated in 1705 and re-chartered as a borough in 1736. In 1753, Lt. Governor Robert Dinwiddie presented the growing city of 4,000 with a long, 104 ounce silver mace.
