Colonial eraMilestone marks five miles from the Boston Town House placed at the current day Soldier's Monument by Paul Dudley in 1735 Shortly after the founding of Boston and Roxbury in 1630, William Heath and three other families settled on land just south of Parker Hill in what is now Jamaica Plain. In the next few years, William Curtis, John May and others set up farms nearby along Stony Brook, which flowed from south to north from Turtle Pond to an outlet in the Charles River marshes in the current filled-in Fens area of Boston. John Polley followed with a farm which he purchased from Lt. Joshua Hewe in 1659 at the site of the present day Soldier's Monument at the intersection of South and Centre streets, closer to the "Great Pond", later known as Jamaica Pond. Later, for services rendered during the Pequot War, Joseph Weld received a grant of 278 acres of land between South Street and Centre Street. His son John later built a home along South Street in what is now the Arnold Arboretum, and his descendants continued to live in the area for many generations. In the late 17th century, the name "Jamaica" first appears for the area of Roxbury between Stony Brook and the Great Pond. There are a number of theories regarding the origin of the name "Jamaica Plain". A well-known theory traces the origin to "Jamaica rum", a reference to Jamaica cane sugar's role in the Triangle Trade of sugar, rum, and slaves. However, a more likely explanation is that "Jamaica" is an Anglicization of the name of Kuchamakin, who was regent for the young Chickatawbut, sachem of the Massachusett tribe.
