Norfolk County, Massachusetts



Norfolk County is a county located in the U.S. state of Massachusetts.  At the 2010 census, the population was 670,850.[1]  Its county seat is Dedham.[2] The county was named after the English county of the same name.[3] Two towns, Cohasset and Brookline, are exclaves.
Norfolk County is included in the Boston-Cambridge-Newton, MA-NH Metropolitan Statistical Area.
Norfolk County is the 28th highest-income county in the United States with a median household income of $81,899. It is the wealthiest county in Massachusetts.
History
Norfolk County, Massachusetts was created on March 26, 1793 by legislation signed by Gov. John Hancock. Most of the towns were originally part of Suffolk County, Massachusetts. The towns of Dorchester and Roxbury were part of Norfolk County when it was created but, as Boston annexed each town, they became part of Suffolk County again. Hingham and Hull were originally part of the Norfolk County legislation but petitioned to remain in Suffolk county and in June 1793 their removal to Norfolk county was repealed. Later, in 1803, they were moved into Plymouth County, Massachusetts. 
The county is the birthplace of four Presidents of the United States (John Adams, John Quincy Adams, John F. Kennedy, and George H.W. Bush), resulting in the moniker "County of Presidents."[4]
Sheriffs

There have been 21 sheriffs of Norfolk County.[5]

Geography
According to the U.S. Census Bureau, the county has a total area of 444 square miles (1,150km2), of which 396 square miles (1,030km2) is land and 48 square miles (120km2) (11%) is water.[6] It is the third-smallest county in Massachusetts by total area. The county is not completely contiguous; the towns of Brookline and Cohasset are each part of Norfolk County but are separated from the majority of Norfolk County (and each other) by either water or other counties. At the county's formation, Hingham and Hull were to be part of it, but joined Plymouth County instead, leaving Cohasset as the initial  exclave of Norfolk County and an enclave of Plymouth County. Brookline became the second exclave of Norfolk County in 1873 when the neighboring town of West Roxbury was annexed by Boston (thus leaving Norfolk County to join Suffolk County) and Brookline refused to be annexed by Boston after the Brookline-Boston annexation debate of 1873.
