Called Pennamaquan by the Passamaquoddy Indians, the area was settled about 1774 as part of Dennysville. It was set off and incorporated on February 4, 1832 by the legislature, which named it after Pembroke in Wales, a community with a history of wooden shipbuilding stretching back to the Middle Ages. With one of the finest harbors in Maine, Pembroke too became a shipbuilding center. Vessels were constructed here as early as 1825. By 1859, when the population was 1,712, there were seven shipyards operating. Most schooners constructed here were used either by the coasting trade or fisheries.
