Jim Kelley supplied the URL of Lincoln`s Thanksgiving Day proclamation
during the American Civil War. It goes back much before Lincoln.

Thanksgiving predates the joint celebration of English colonists and
American Indians at Plymouth in 1621. Thanksgiving gatherings have
occurred throughout the world and throughout history. In America, the
natives traditionally had several of these festivals a year long before
the Europeans arrived. The English colonists did not call the 1621 event
a "thanksgiving". They actually had their first thanksgiving in the
summer of 1623 for rain which ended a long drought.

Happy Thabksgiving!
