EARLY COLONIAL
This MUST, for sheer quality, include the people at Plimoth Plantation. Their extensive site should help most teachers however for quick reference I suggest the following--
Tony Kelso (Education Outreach) kelso@plimoth.org
Kim Van Wormer (Education) education@plimoth.org
Walt Woodward (Education) woodward@plimoth.org
 

ENGLISH CIVIL WAR
Co-ordinators for the ECWA are---
Keith Frye (NY, NJ, PA)
Email: kmfrye@carroll.com

Bob Giglio (MD, DE, PA, VA)

The above group not only covers this little known period of American history but also covers the early colonial life, including Dutch and Swedish, of nationalities involved.

AMERICAN REVOLUTION

Probably the second largest of the historical groups and covers the whole of the US. At present the best contact is via the commander of "The British Brigade" who is both a good friend and by profession a teacher. He will no doubt try to put you in touch with a nearby British unit and/or one of those Nasty American rebellious units.
