Records for colonial Delaware are plentiful and varied. But according to the Historical Society of Delaware’s website, “Delaware’s rich and complex colonial history offers genealogists a special challenge. Early colonial documents might be found in many places, including the archives of New York State and Pennsylvania, as well as those of Sweden, the Netherlands, and Great Britain.”

The Delaware Public Archives (DPA) has documents from the Swedish colonial period, 1638 to 1655; the Dutch settlement, 1655 to 1664; the Duke of York regime, 1664 to 1682; and the Penn Proprietorship, 1682 to 1776, with the majority of their holdings dating from statehood in 1776.

Use the Archive’s online guide to the collections and search the database, which is just a portion of the holdings, for types of records — not for your ancestors’ names. For example, type in “birth records 1864” to find out where your ancestor’s birth certificate may be located.

DPA has an index to marriages, births and deaths, from marriage bonds, church and Bible records, and newspapers from 1680 to the present. Statewide registration of Delaware births began in 1861, was discontinued in 1863 and resumed in 1881. Marriage records start as early as the 1700s for some towns; statewide registration began in 1847 and was generally complied with by 1913. Statewide death registration began in 1881 and was generally complied with by 1890. You can access birth records older than 72 years and marriages and deaths older than 40 years from the DPA. Look for microfilmed vital records at the Family History Library , too.


The 1790 US census was Delaware’s first, but most schedules were destroyed. You’ll find a reconstruction from tax and assessment records in Reconstructed 1790 Census of Delaware by Leon de Valinger Jr. (National Genealogical Society). Early tax records also can substitute for colonial censuses. Delaware didn’t take state censuses.

During the colonial period, Presbyterians, English Quakers, Baptists, Catholics and Methodists settled in the area. Many church records have been published. Also look for original records and indexes at various repositories including the DPA and Historical Society of Delaware (HSD).

The DPA is the primary facility for noncurrent state and local government records, such as probate records, court documents (civil, criminal, naturalization, indenture) and municipal papers (minutes, accounts, reports). The collection inventory is online at Original deeds and mortgages from 1680 are also there, as are miscellaneous genealogical manuscripts and a large collection of grave records known as the Tatnell Tombstone collection. Staff member Russ McCabe emphasizes that the archives has a “fairly large and growing library of printed and unpublished genealogies.”


“Visit both the Historical Society of Delaware and the Delaware Public Archives,” says Constance Cooper, librarian at the HSD. The HSD is a private, nonprofit organization that collects nongovernmental records such as genealogies, manuscripts and church records. Its website features a Guide to Research in the Delaware Historical Society Library, an online instruction manual. Cooper says “a personal visit is the best way to research your Delaware families, because staff provides an orientation to the collection as well as assistance.” One helpful on-site resource is the Genealogical Surname File, a card catalog of names and references arranged alphabetically by surname. The cards were compiled over the years from newspapers printed before 1850, books, journals, church records and other sources.

The Delaware Genealogical Society compiles information on Delaware research, including the Delaware Genealogical Research Guide, 3rd edition, by Thomas P. Doherty (Delaware Genealogical Society, 2002). Search the website for names entered into the Delaware Families Project.

Delaware has only three counties — New Castle, Kent and Sussex — so research in the state initially appears simple. But William Penn decided to divide the colony into “hundreds” for taxation. This old English land division is explained by the Delaware Genealogical Society website as a “land division which is smaller than a county or shire and larger than a tithing. It comprises 10 tithings of 10 freeholder families each, or 100 families.” Hundreds are roughly equivalent to townships in other states. Once used as judicial and legislative districts, they remain now only as the basis for property tax assessment.
