Records at the New Haven County Courthouse
LEARN MORE ABOUT Probate Records, Land Records, Marriage Records & Court Records

PLEASE READ!! Please call the clerk's department to confirm hours, mailing address, fees and other specifics before visiting or requesting information because of sometimes changing contact information.

NOTE: Counties were abolished officially in 1959 though their purpose had been chiefly to define county court districts. For genealogical research purposes, counties become necessary when using the federal census returns, since they are all cataloged by county.

All deeds, vital records, and probate records for all Connecticut towns are available to 1900 on microfilm at the Connecticut State Library or through the FHL. See Towns Page for address and Phone Numbers of Towns. See also Connecticut Towns and Their Establishment

Those matters not in the realm of the superior court were heard by the county courts (initially called prerogative or common pleas). The county court, begun in 1666, was abolished in 1955, and its functions were divided between justice courts and superior courts. Most of the county records, to its abolition date, are at the Conneticut State Library.

New Haven County Military Records - LEARN MORE ABOUT Connecticut Military Records

Search Online Click Here to Search Connecticut Military Records! - Military and civil service records provide unique facts and insights into the lives of men and women who have served their country at home and abroad.

   The uses and value of military records in genealogical research for ancestors who were veterans are obvious, but military records can also be important to re-searchers whose direct ancestors were not soldiers in any war. The fathers, grandfathers, brothers, and other close relatives of an ancestor may have served in a war, and their service or pension records could contain information that will assist in further identifying the family of primary interest. Due to the amount of genealogical information contained in some military pension files, they should never be overlooked during the research process. Those records not containing specific genealogical information are of historic value and should be included in any overall research design.

New Haven County Tax Records - LEARN MORE ABOUT Tax Records

   Taxes were levied for personal property and land through most of Connecticut's history. The town assessor (or lister) made annual lists or rates of all taxables. This generated a considerable number of tax lists across time, but the Connecticut State Library has a list of various tax records still at the town clerk's offices. The Connecticut Historical Society and the genealogical collections throughout the state have some records.

A highly valuable tax record for Connecticut is the U.S. Direct Tax for 1798. The records are extant for nearly half of the towns with some also having rate lists for 1813, 1814, 1815, and 1816. The original booklets indicate rate based on land, dwellings, and personal property, the latter of which is usually itemized. Later years indicate out-of-state owners. The records have not been microfilmed as a group, but the originals can be researched at the Connecticut Historical Society.

New Haven County Genealogical Addresses - LEARN MORE ABOUT Connecticut Genealogical Addresses

   The Repositories in this section are Archives, Libraries, Museums, Genealogical and Historical Societies. Many County Historical and Genealogical Societies publish magazines and/or news letters on a monthly, quarterly, bi-annual or annual basis. Contacting the local societies should not be over looked. State Archives and Societies are usually much larger and better organized with much larger archived materials than their smaller county cousins but they can be more generalized and over look the smaller details that local societies tend to have. Libraries can also be a good place to look for local information. Some libraries have a genealogy section and may have some resources that are not located at archives or societies. Also, take a special look at any museums in the area. They sometimes have photos and items from years gone by as well as information of a genealogical interest. All these places are vitally important to the family genealogist and must not be passed over.

New Haven County Church & Cemeteries - LEARN MORE ABOUT Connecticut Church & Cemetery Records

Search Online Click Here to Search Connecticut Obituary Records! - This database is a compilation of obituaries published in U.S. newspapers, collected from various online sources. Obituaries can vary in the amount of information they contain, but many of them are genealogical goldmines, including information such as names, dates, places of birth and death, marriage information, and family relationships.

   There are many churches and cemeteries in New Haven County. Some transcriptions are online. A great site is the New Haven County Tombstone Transcription Project.

Early Connecticut settlers established the Congregational church as the tax-supported state church until 1818 when the state constitution was accepted abolishing the connection between church and state. Sometimes, if one parish was getting too large, a second was formed that became a precursor to a new town with the permission of the general assembly. Other denominations followed eventually, particularly the Baptists and Episcopalians from Rhode Island on the eastern border with Connecticut. Information in Connecticut's church records has often been found to be more informative, complete, or accurate than the town vital records.

Centralization is the norm for Connecticut's cemetery records. The Connecticut State Library holds the Hale Collection containing over one million gravestone inscriptions. The project to collect these began in 1916 by Charles R. Hale but was continued by act of the General Assembly and the WPA through the 1930s. While clearly many stones had been lost or destroyed by that time, over 2,000 cemeteries were located state-wide and included in the collection. Each town's inscriptions are bound in separate volumes, but an alphabetical index across towns is available. Both have been microfilmed and are available through the FHL.

County History - New Haven County, south-central Connecticut, U.S. It is bordered to the south by Long Island Sound, to the southwest by the Housatonic River, and to the southeast by the Hammonasset River. The county's terrain consists of rolling plateaus and river valleys to the north and coastal lowlands to the south; the sound contains several islands. Other waterways include the Naugatuck, Quinnipiac, and Wepawaug rivers as well as Lakes Gaillard, Saltonstall, and Quassapaug. Parklands include Naugatuck State Forest Reserve and Sleeping Giant, West Rock Ridge, and Hammonasset Beach state parks.

English Puritans founded New Haven colony in 1638, and it reluctantly joined Connecticut colony (1665) and became a county in 1666; county government was abolished in 1960. Initially dependent on agriculture and maritime trade, the economy became industrialized in the 19th century, spurred by the inventions of New Haven residents Eli Whitney, who developed the concept of mass-producing interchangeable parts, and, later, Charles Goodyear, who created the vulcanization process for rubber. Manufacturing remains important, although services and trade have passed it in terms of value.
