Duty in the Cause of Liberty is a four-book series set during the American Revolutionary War. The books follow Isaac Frye, a farmer from Wilton, New Hampshire who became a Continental Army officer and serves for the entire war.

This site adds to the details in the books with my research, maps and genealogical information, including lists of patriots from New Hampshire that SAR, DAR, and other colonial lineage societies require.

The books are available for sale on Amazon.com and can be read for free with Kindle Unlimited.
