Somerville is a city in Middlesex County, Massachusetts, United States, located just north of Boston. As of the 2010 census, the city had a total population of 75,754 and was the most densely populated municipality in New England. It is also the 17th most densely populated incorporated place in the country. It was established as a town in 1842, when it was separated from the urbanizing Charlestown. Somerville was a 2009 All-America City Award recipient.
Somerville was first settled in 1630 as part of Charlestown. It was known as "Charlestown beyond the Neck" because it was part of the Massachusetts mainland, not the Charlestown Peninsula. (Charlestown Neck was the narrow strip of land that joined the two.) The incorporation of Somerville in 1842 separated the largely rural town from the urbanizing Charlestown.
The original choice for the city's new name after breaking away from Charlestown was Walford, after the first settler of Charlestown. However this name was not adopted by the separation committee. Mr. Charles Miller, a member of this committee, proposed the name "Somerville" which was chosen. It was not derived from any one person's name. A report commissioned by the Somerville Historical Society found that Somerville was a "purely fanciful name" (though "Somerville" is a surname of Franco-British origin).
