Letter to New York Times Requesting Correction (re: The Birth of Thanksgiving)

The Birth of Thanksgiving -- correction, please
http://opinionator.blogs.nytimes.com/2013/11/28/the-birth-of-thanskgiving/?_r=0
Dear Editor:
The first Thanksgiving was September 8, 1565 in St. Augustine, Florida,
involving newly landed Spanish settlers and Native Americans, some 55 years
before Plymouth.
America's first Hispanics, first African Americans, first Catholics and first
Jews attended the first Thanksgiving here after 800 settlers landed and said the
first Catholic Mass on these shores.
The Anglophilic Plymouth "First Thanksgiving" myth is both ethnocentric and
wrong.
Please correct this error.
Thank you!
With kindest regards, I am,
Sincerely,
Ed Slavin
