Genealogical Research in Connecticut

Genealogy Research Connecticut

Connecticut has a long and colourful history, making it especially interesting to conduct research in the state. While researching Connecticut genealogy records presents a unique set of challenges; it also has its own unique rewards. There are many historical and genealogical records available for the state, and we know just where to find them. To get you started in tracing your ancestry, we’ll introduce you to those records, and help you to understand:

  • What they are
  • Where to find them
  • How to use them

These records can be found both online and off, so we’ll introduce you to online websites, indexes and databases, as well as brick-and-mortar repositories and other institutions that will help with your research in Connecticut. So that you will have a more comprehensive understanding of these records, we have provided a brief history of the “Constitution State” to illustrate what type of records may have been generated during specific time periods. That information will assist you in pinpointing times and locations on which to focus the search for your Connecticut ancestors and their records.

A Brief History of Connecticut

Connecticut as we know it today was first settled by Europeans when the Dutch built a small fort on the site of modern day Hartford. As English settler began to move into the area the Dutch abandoned their post and members of the Plymouth colony established a settlement on the site of Windsor in 1633.

European settlement was resisted by the Native Pequot tribe which led to their defeat by the English in the Pequot War of 1637. In 1643 the New England Confederation, an informal union for mutual defences was formed when New Haven and Connecticut colonies united with the Massachusetts Bay colony. Connecticut won its legal right to exist as a corporate colony when Governor John Winthrop secured a royal charter in 1662.

Connecticut continued to grow through the seventeenth century, yet by the mid 18th century a bitter feud had developed between conservatives and radicals in the colony. During the Revolutionary War Connecticut served as the chief supply area for the continental Army, and several towns such as Danbury, New Haven, New London, and Fairfield were attacked by the British.

After the Revolutionary War Connecticut prospered, its ports bustling with business and textile mills thriving. In 1788 Connecticut became the 5th US State, even though opposing the foreign policy of presidents Thomas Jefferson and James Madison. Connecticut opposed the War of 1812, going as far as refusing to allow its militia to leave the state. The War 12 severely hurt exports, though the end result promoted rapid growth of industry.

Connecticut had very strong anti-slavery sentiments, enacting legislation that any slave that every black born after 1 March 1784 would be free at age 25. The state finally abolished slavery in 1848. There was no question about supporting the union cause during the Civil War, and Connecticut sent almost 60,000 troops into battle. Perhaps the state’s biggest role during the Civil War was the manufacturing of much needed rifles, ammunitions, and uniforms, which inevitably signaled Connecticut’s emergence as a manufacturing giant.

The state continued to donate its manufacturing resources to the war efforts of both World Wars, and the state prospered by supplying munitions, weapons and other supplies. Manufacturing began to decline during the 1970’s as the growth of the financial, real estate, insurance, and service industries took root. Wealth was limited to the suburbs however, while central cities such as Bridgeport have failed to the point of bankruptcy. The 1990’s saw the development of Native American casinos, which have since supplanted defense industries as the state’s main economic engine.

Famous Battles Fought in Connecticut

Several battles between the Revolutionary forces and the British took place in Connecticut. Additionally there are many accounts of the battles fought during the Pequot War. These battle accounts can be very effective in uncovering the military records of your ancestor. They can tell you what regiments fought in which battles, and often include the names and ranks of many officers and enlisted men. Following are some of the most famous battles fought in Connecticut and links to useful information about them.

Common Connecticut Genealogical Issues and Resources to Overcome Them

Boundary Changes: Boundary changes are a common obstacle when researching Connecticut ancestors. You could be searching for an ancestor’s record in one county when in fact it is stored in a different one due to historical county boundary changes. The Atlas of Historical County Boundaries can help you to overcome that problem. It provides a chronological listing of every boundary change that has occurred in the history of Connecticut.

Name Changes: Surname changes, variations, and misspellings can complicate genealogical research. It is important to check all spelling variations. Soundex, a program that indexes names by sound, is a useful first step, but you can't rely on it completely as some name variations result in different Soundex codes. The surnames could be different, but the first name may be different too. You can also find records filed under initials, middle names, and nicknames as well, so you will need to get creative with surname variations and spellings in order to cover all the possibilities. For help with surname variations read our instructional article on How to Use Soundex.

Historical Connecticut Maps and Gazetteers

Maps are an integral part of genealogical research. They help us to locate landmarks, towns, cities, parishes, states, provinces, waterways and roads and streets. They also help us to determine when and where boundary changes might have taken place, and give us a visualization of the area we’re researching in. For locating place names, a gazetteer is the best possible resource for any genealogist. Gazetteers are also sometimes called “place name dictionaries”, and can help you to locate the area in which you need to conduct research.

Connecticut Genealogical Records

Birth, Death, Marriage and Divorce Records

Birth, Death, Marriage and Divorce Records – Birth, death, and marriage records are the most basic, yet most important records attached to your ancestor. They are generally referred to as vital records as they record vital life events. The reason for their importance is that they not only place your ancestor in a specific place at a definite time, but potentially connect the individual to other relatives.

Census Reports

Census records are among the most important genealogical documents for placing your ancestor in a particular place at a specific time. Like BDM records, they can also lead you to other ancestors, particularly those who were living under the authority of the head of household.

Connecticut census records exist from 1670 and many images and indexes can be viewed online.

Connecticut Church Records

Church and synagogue records are a valuable resource, especially for baptisms, marriages, and burials that took place before 1900. You will need to at least have an idea of your ancestor’s religious denomination, and in most cases you will have to visit a brick and mortar establishment to view them.

Most church records are kept by the individual church, although in some denominations, records are placed in a regional archive or maintained at the diocesan level. Local Historical Societies are sometimes the repository for the state’s older church records. Below are links archives that maintain church records, as well as a few databases that can be viewed online.

The Family History Library contains many church records from a variety of denominations on microfilm.

Connecticut Cemetery Records

As convenient as it is to search cemetery records online, keep in mind that there are a few disadvantages over visiting a cemetery in person. They are:

  • Tombstone information is not always accurately transcribed
  • The arrangement of the graves in a cemetery can be crucial as family members are often buried next to each other or in the same grave. This arrangement is not always preserved in the alphabetical indexes that are found online.

With that information in mind, the following websites have databases that can be searched online for Connecticut Cemetery records.

Missing Matriarchs – Resources for Researching Female Connecticut Ancestors

Looking for female ancestors requires an adjustment of how we view traditional records sources. A woman’s identity was often under that of her husband, and often individual records for them can be difficult to locate. The following resources are effective in locating female ancestors in Connecticut where traditional records may not reveal them.

Marriage and Divorce Records

The earliest marriage records were recorded by the towns and often mixed with land records. It wasn’t until 1849 that town and probate clerks were ordered to record marriages. In addition to original town records, the following indexes can be found at the Connecticut State Library:

  • Barbour Index to Vital records, (film 0002887 ff.)
  • Hale Collection of Vital records (film 0003076 ff.)

Divorces were first recorded in the General Court of Connecticut Colony, and in the Court of Magistrates in New Haven Colony. The Superior Court was given jurisdiction in 1711, and later records are held by the Clerk of the Superior Court in the county where the divorce was granted. Many records of divorce have been filmed at the Connecticut State Library and are as follows:

  • Fairfield County, 1720-1799 (film 1673219 ff.)
