One of the major sources for this index is the the journal of Francois Baby, Gabriel Taschereau, and Jenkin Williams.  Several months after the Battle of Quebec in May 1776, Governor Carleton ordered a survey to identify the Canadians who had helped the Americans.  Francois Baby, Gabriel Taschereau, and Jenkin Williams travelled the province and counted the Canadians who actively provided such help.  They recorded the specific actions of those who assisted the Americans in a journal, and an English translation of the journal was published in 2005 in the book "Quebec During the American Invasion, 1775-1776."  This book can be ordered from Barnes & Noble.
