Since there is a lot of activity on this site, I thought I would provide some information on the townships from the beginning of Phyllis B. D'Autrechy's book More Records of Old Hunterdon County, Hunterdon County Historical Society, 1998. Depending upon the time period your ancestors may not have moved but the township boundaries may have changed. For example they may have lived in Amwell in the early 1700's but it was called Kingwood after 1746. "Hunterdon Co. was formed in 1713/14 from Burlington Co. In 1738 more land was annexed from Morris Co. At that time Hunterdon Co. had the following townships: Alexandria, Amwell, Bethlehem, Hopewell, Kingwood, Lebanon, Maidenhead, Reading, Tewksbury and Trenton. In 1838 Hopewell, Maidenhead and Trenton were taken to form Mercer Co. Hunterdon Townships then were Alexandria, Bethlehem, Clinton, Delaware, East Amwell, Franklin, Holland, Kingwood, Lebanon, Raritan, Readington, Tewksbury, Union, and West Amwell."

There is a book which was published by the NJ Geological Survey which gives the dates for the formation of the counties & townships and subsequent changes. The price of the book is $15.00 which includes shipping.
