Bronx County Genealogy Search
Bronx County genealogy research follows a different path than most New York counties because the Bronx is one of the five boroughs of New York City. The county did not exist as a separate entity until 1898. Records before that date fall under the old towns of Kingsbridge, West Farms, and Morrisania, which were part of Westchester County. Today, the NYC Municipal Archives, the Bronx County Clerk, and several local history groups hold the records you need for Bronx genealogy. Millions of digitized records are also available online through the city's archives portal.
Bronx County Genealogy Overview
Bronx County Records at NYC Municipal Archives
The NYC Municipal Archives is the main source for historical Bronx County genealogy records. Birth records cover 1898 to 1909. Death records run from 1898 to 1948. Marriage records span 1898 to 1949. All of these start in 1898 because that is when the Bronx joined New York City as a borough. Records for the area before 1898 fall under the old Westchester County towns and are also held at the Municipal Archives.
The archives have digitized millions of records. PDF copies of digitized records can be emailed in about five days. In-person research at 31 Chambers Street, Room 103, New York, NY 10007 is by appointment only. The office is open Monday through Thursday, 9:00 AM to 4:30 PM and Friday 9:00 AM to 1:00 PM. Phone is 311, or (212) 639-9675 from outside NYC. Email is research@records.nyc.gov.
About 25 percent of births before 1910 were never reported to the city. So gaps in the early record are common. If you cannot find a birth record, try church records or census data as a backup.
