Notes: In 1789, Revolutionary War Patriot Paul Trapier donated a tract of land on North Island for the establishment of the Georgetown Lighthouse. However, the newly formed Lighthouse Service did not take immediate advantage of the offer, and another decade passed before construction began on the Georgetown Lighthouse.
The seventy-two-foot, pyramidal tower, constructed of Cypress wood, was finished in the early part of 1801, during the final days of John Adams' presidency. Besides the tower, a two-story keeper's dwelling was built along with a tank for holding the whale oil that fueled the lighthouse's lamp. The wooden tower's life was cut short by a violent storm in 1806. 
Several years passed before a replacement structure was built. A marble plaque positioned above the door records the names of those who undertook the work on the tower and records the year of its erection as 1811. This time the seventy-two-foot tower was constructed of brick, greatly reducing the chance that a big, bad gale would blow the lighthouse down. The staircase that spirals upwards inside the stout brick tower is made of stone. In 1857, the tower was modified to display a fourth-order Fresnel lens.
When the Civil War broke out, the Confederates used the Georgetown Lighthouse as a lookout station, until Union forces captured it in May of 1862. The lighthouse was heavily damaged during the North-South conflict, and as part of the post-war repair work, the tower was heightened to eighty-seven feet.
