I have just read a great article in the New England Ancestors magazine, Spring 2002 issue pp 11-16 on this subject. The article is writtne by David Curtis Dearborn of NEHGS and includes a list of suggested reading on the subject. Here are a couple of them. Holbrook, Stewart H., they Yankee Exodus: an Account of Migration from New England Davenport, David Paul, The Yankee Settlement of New York, 1783-1820," Genealogical Journal, 17 (1988-89):63-88 -- Kind regards, Sandy from Colorado
