New Hampshire Counties

Many New Hampshire family records can be found online and at large state level archives and libraries in Concord. Many millions of records aren't yet available online, though, and many of these are awaiting your discovery at the local level at county courthouses, historical societies, churches, town clerks' offices, cemeteries, and elsewhere in New Hampshire. To find these and other records, click on the links below to find more information about the specific counties where your ancestors lived in New Hampshire. You'll find information on these pages that will lead you to the specific documentation you're searching for.

It is important to keep in mind when doing research that the names and boundaries of certain counties in New Hampshire have changed over the past few hundred years. Your ancestors may have lived on a certain farm in one county and when borders were redrawn records relating to your family history might have been located in another area entirely. When searching for land, court, tax, and other records it is also a good idea to search for these records in adjacent counties. Following is a complete list of New Hampshire's 10 counties along with their formation dates, county seats, and names of parent counties.
