From the Dutch Nieuwe Dorp, ‘New Village’.
New Dorp was founded in the early 1670s, when the English resurveyed the existing Dutch settlement of Oude Dorp, ‘Old Village’ (today’s Old Town), and laid out new lots along the South Shore, settled mainly by Dutch families. The new lots became known as Nieuwe Dorp, later anglicised as New Dorp. The Dutch ‘dorp’ is related to the English ‘thorpe’ found in place names.
