Manuscript map of a plan of Ann (now Park) Street in Portland, as it was about 1802, showing the property of Thomas Robison. Thomas Robison, a Scottish immigrant lived on Falmouth Neck (Portland) before the American Revolution. A Loyalist, Robison went to Canada and served in the British Army during the war. He returned to Falmouth Neck in 1783 and became a prosperous merchant and distiller, engaging in all aspects of the triangle trade. Robison opened Ann Street from Main (Congress) Street to the waterfront. This plan was drawn at the time of the pending sale of his holdings and subsequent (second) departure from Portland.
