Where to find New Hampshire census records, immigration records, land records, maps, vital records and more.
New Hampshire's records date from the early colonial period. Town and city clerks kept track of vital records, but coverage is spotty. An every-name index to early vital records exists, but doesn't include 17 towns. Microfilm copies can be found at the New Hampshire State Library, the New England Historic Genealogical Society in Boston, and through the Family History LIbrary (FHL) http://www.familysearch.org
Civil Registration in 1866 required cities and towns to send copies of their birth and death records to the state, but total compliance didn't occur until 1905, with the establishment of the Bureau of Vital Records. Originals remain in most town and city halls. Births prior to 1901 and marriages, divorces, and deaths before 1949 are open to the public.
