We were stumped. Then after months of exhaustive Googling, we hit the jackpot: THE AMERICAN STATE PAPERS: Documents, Legislative and Executive of the Congress of the United States, from the First Session of the First to the Third Session of the Thirteenth Congress, Inclusive: Commencing March 3, 1789, and Ending March 3, 1815.

From an 1804 report in THE AMERICAN STATE PAPERS:
Our own Government has attended to the erection of light houses, with a vigilant eye. Already their number on our extended sea coast amounts to thirty-one...Those lighthouses, listed north to south, were in a statement "shewing" expenses:
New Hampshire: Portsmouth; Massachusetts: Boston, Nantucket, Nantucket Beacon, Cape Roge [Cape Pogue], Thatcher's Island, Plum Island, Plymouth, Seguin Island [now in Maine], Baker's Island, Cape Cod, Wigwam Point [Annisquam], Gayhead; Rhode Island: Newport; Connecticut: New London, Faulkner's Island, Lynde's Point; New York: Montauk, Sandy Hook, Eaton's Neck; Delaware: Cape Henlopen; Virginia: Cape Henry, Smith's Point, Old Point Comfort; North Carolina: Cape Fear, Cape Hatteras, Shell Castle [off Ocracoke Island]; South Carolina: Charleston, George Town; Georgia: Tybee.In 1811 Winslow Lewis won a contract to outfit all U.S. lighthouses with his patented lighting system, which was a cheap imitation of the Argand system used in Europe (an example of the need for international copyright protection). He listed 45--in no discernible order, whether geographical, alphabetical or financial:
Cape Page [Cape Pogue]
Chatham, 2 lights
Plymouth, 2 lights
Baker Island, 2 lights
Newburyport, 2 lights
New Point Comfort
Old Point Comfort
Little Gull Island
Five Mile Point
Fair Weather Point
