New Jersey Genealogy Search at a Glance

New Jersey family history has an early start in the vital records: the state began statewide registration in May 1848, decades before most states, and the New Jersey State Archives in Trenton holds the births, marriages and deaths from 1848 through the early 1900s with free online indexes, along with the colonial records from the 1660s, the state censuses of 1855 through 1915 and the county records of 21 counties on microfilm. The Archives' online searchable databases are among the most useful in the country.

New Jersey's proprietary period left East Jersey and West Jersey land records, and the county clerks and surrogates have kept deeds and probate since the counties formed in 1683.
