Hi Gail, Barker has pulled a lot of material together from many sources. Information is from Pearson's books, church baptism and marriage records, family histories and any place else he could find data. One problem is that there are a number of errors. The preferred source for Palatine or Mohawk information is Henry Z Jones's books. "Palatine Families of NY" and "More Palatine Families". These books are available in many libraries. Another source for information is KINSHIP. Art Kelly has published many baptism and marriage books for the eastern New York area. His web address is www.kinshipny.com The next source is published genealogies. At least 250 families have published one or more family histories. A number of them are available from the Herkimer Historical Society. 400 Main St. Herkimer, NY 13350.
