"The King's Royal Yorkers

 
The King's Royal Yorkers is the largest of several Living History groups that are proud members of the Canadian Museum of Applied Military History.

This historical project recreates Loyalist soldiers and their families who fled to Canada to form the first Loyalist regiment raised on Canadian soil. The American war of 1775 to 1783 saw the King's Royal Yorkers on active service with the Northern Department."

I just learned that my great, great, great, great grandfather joined them on August 18, 1777.

Also learned, btw, that 2010 is the 300th anniversary of my family's arrival in America, October 1710, from Palatine (Pfalz) Germany.
