Cape Cod turkey

America's First Thanksgiving in Berkeley?
The first true American Thanksgiving feast took place on this date in 1619 at Berkeley Plantation, in what is now Virginia — about a year before the better remembered 1620 arrival of the pilgrims in Massachusetts. On this date, thirty-eight colonists from England's Berkeley Parish who had dropped anchor in the James River came ashore, led by Captain John Woodlief. He spoke for the group: "Wee ordaine that the day of our ship's arrival at the place assigned for plantacon [plantation] in the land of Virginia shall be yearly and perpetually kept holy as a day of thanksgiving to Almighty God." But it was not until November 26, 1789, that what Americans call Thanksgiving was first commemorated as a national holiday, at the behest of George Washington, to celebrate the adoption of the US Constitution. The date remained until Abraham Lincoln changed it to the variable-date Thursday format in 1863.
That's US Constitution, the document, not U.S.S. Constitution, the ship.
