Letters of Indenture
Lesser-known resources like letters of indenture can offer rich, detailed insights; especially when researching early immigrants. These contracts, used primarily in the 17th through early 19th centuries, documented agreements between indentured servants and their masters and often reveal personal details not available elsewhere.
What Are Letters of Indenture?
A letter of indenture is a legal contract between two parties, usually binding one to work for another for a set period in exchange for something of value. In the colonial and early post-colonial eras, this “value” was often transatlantic passage, food, shelter, or training in a trade. The indentured party; often a young, impoverished European; agreed to labor under specific conditions for a number of years.
Unlike general labor contracts, letters of indenture were frequently recorded by local authorities or shipping agents and sometimes even notarized. They are called “indentures” because the document was often written in duplicate on a single sheet of paper, then torn in a jagged line so that each party had a matching copy; a physical way to validate the authenticity of the agreement.
Why Indenture Records Matter for Genealogists
For genealogists, these documents are more than just employment agreements; they’re a treasure trove of biographical data, especially for immigrants whose arrival might otherwise go unrecorded.
Here’s what you might find in a letter of indenture:
- Full Name of the Indentured Person: Often including alternate spellings or original spellings from the homeland.
- Age or Approximate Age: Especially useful for estimating birth years in the absence of baptismal records.
- Place of Origin: Sometimes general (e.g., “Ireland” or “the Palatinate”, a German jurisdiction), but occasionally specific, naming a village or town.
- Name of the Master or Employer: Which can lead to further research in local land records, wills, or business directories.
- Length and Terms of Service: Revealing conditions such as duties expected, prohibitions, or benefits after service.
- Date of Contract: Giving a firm anchor point in the timeline of migration.
Where to Find Indenture Records
Though not as widely digitized as other documents, letters of indenture can be found in several types of archives:
- Colonial Court Records: Many indenture contracts were filed with courts for legal enforcement.
- Shipping Manifests and Port Records: Some shipping companies maintained copies of these agreements, especially when they facilitated passage in exchange for future labor.
- Land Office Archives: Masters sometimes received land grants in exchange for importing indentured laborers. These transactions were recorded.
- Private Collections and Family Papers: Wealthy colonial families often kept detailed records, including original indenture agreements.
- Library Special Collections: Institutions such as the Library of Congress or historical societies may hold transcriptions or original copies.
When researching, start by identifying the region and time period in which your ancestor may have been indentured, then check the county or colonial archives. State archives and university libraries are often underutilized sources for these materials.

Tips for Using Indenture Records in Your Research
- Cross-reference Masters: Once you identify the name of a master or employer, research their household. Indentured servants often lived with or near their employers, so you may find them in household or church records.
- Track Emancipation or Land Transfer Records: At the end of a contract, some indentured servants received “freedom dues,” which might include tools, clothing, or even land. These transactions were sometimes documented and can help track an ancestor post-indenture.
- Look for Group Indentures: Sometimes entire groups were indentured together, such as orphaned children or religious refugees. Knowing this can lead to cluster research with others from the same origin.
- Check for Naturalization Petitions: After completing their service, many indentured immigrants applied for naturalization. These petitions can sometimes name previous masters or service locations.
- Use Name Variants Liberally: Names were frequently misspelled or anglicized. Search under multiple spellings and consider phonetic variations.
Historical Context Adds Value
Understanding the historical context behind indentured servitude can also help. For instance, periods of war, famine, or political upheaval in Europe often correlate with spikes in indentured immigration. The Irish potato famine, religious persecution of German Palatines, or economic depression in England all led to waves of indentured workers coming to the New World. Placing your ancestor within these larger movements can illuminate not just where they came from, but why they came.
Final Thoughts
Letters of indenture are often overlooked by modern researchers, but they remain a rich and underutilized source for genealogists seeking to understand the lives of early immigrants. These records can bridge gaps in timelines, confirm geographic origins, and even reveal character through the specific terms of agreement. If your ancestor arrived before 1850 and doesn’t appear in passenger lists or early census records, take a closer look at indenture records; they just might hold the missing link in your family history.
