It may be a day late, but this seems to be a pretty good Thanksgiving Day Primer by Kirby Anderson.
Here is a great quote found in the primer by Daniel Webster given on December 22, 1820 at the 200 anniversary of the landing of the Pilgrims at Plymouth Rock.
“Let us not forget the religious character of our origin. Our fathers were brought hither by their high veneration for the Christian religion. They journeyed by its light, and labored in its hope. They sought to incorporate its principles with the elements of their society, and to diffuse its influence through all their institutions, civil, political, or literary.”
