Stories abound as to how Jamaica Plain derived its name; some trace it to the flow of rum shipments to the port of Boston following Oliver Cromwell's seizure of Jamaica in 1660, but whatever the true origin of the name, the area has a rich and colorful history that flows from its rural, pastoral beginnings in the 17th century and into the 21st. Jamaica Plain today is one of Boston's great suburban neighborhoods, but it has not always been connected to the city. Jamaica Plain first became a part of Roxbury, and later West Roxbury, and served as a summer playground for influential Bostonians before becoming part of Boston in 1874. The neighborhood's beauty has been protected by such visionaries as Benjamin Bussey, who bequeathed his estate to Harvard College for what is now the Arnold Arboretum, and Henry A.S. Dearborn, the former mayor of Roxbury who established the Forest Hills Cemetery. Today, the neighborhood is a bustling suburban spot that has preserved its natural beauty and resources.
