The former towns of
Enfield,
Greenwich and
Prescott no longer exist in any form; they were legislated out of existence in the 1930s before being flooded by the Quabbin Reservoir, which supplies water to the
Boston area. Longmeadow and
Southwick are in
Hampden County, not
Hampshire County. Florence and
Leeds are villages or neighborhoods in Northampton. South
Hadley Falls and South
Worthington are neighborhoods/villages in South
Hadley and
Worthington. There are dozens of other villages, former villages, and named neighborhoods in present-day
Hampshire County towns, in addition to the ones named above.
