About half of Parker's Island provided grazing land, and some residents raised livestock and produced butter and cheese. In 1858, there were two sawmills, two shingle mills, a pailmaker and a shipbuilder. But the merchant marine and fishing were the town's principal occupations. By 1841, all the other parts of Georgetown had been set off and incorporated as towns, leaving Parker's Island with sole claim to the ancient name. Situated between the mouths of the Sheepscot and Kennebec rivers on the Gulf of Maine, Georgetown developed into a summer resort, attracting a number of prominent artists. The island is a noted site for bird watching.
