Different areas of color represent ethnicities. Red is labeled French-Canadian, yellow is for Portuguese, blue for Polish, green for Greek, and light orange for Jewish.

Extended Description

Lowell National Historical Park is located under the peak of an upside down- V-shaped bend of the Merrimack River. The largest shaded area is in the crook. It is labeled Little Canada, and it includes two arms reaching up and across the river.

Just south of Little Canada, a portion of the park is outlined by a gray dashed line and labeled Acre. Text here also reads “Irish in 1840.” A green area within the outline indicates that most of the Greek population was located there.

The first yellow area is just to the bottom right of Little Canada, indicating the presence of a Portuguese population. Just across the river from the area highlighted in yellow is a slightly bigger area highlighted in blue. This is the first of three round areas, all separated by the river and other bodies of water, labeled as Polish.

Below this is a rectangular area outlined by a gray dashed line and labeled Chapel Hill. Another note in the gray area reads “Irish in 1840.” A yellow bean-shaped area partially overlaps this to represent a larger Portuguese population. West of Chapel Hill is a light orange area representing the Jewish population.
