How to Properly Cite in Genealogy

What Is a Genealogical Citation?

A genealogical citation is a precise description of the source you used to support a fact. It does not merely name a website or an archive, but clearly identifies the specific record consulted and explains how that record was accessed.

A proper citation answers three essential questions that guide both its structure and its content:

• What exactly did I use?
• Where can it be found again?
• What kind of source is it?

Together, these questions ensure that another researcher can locate the same record and evaluate its reliability. When research is conducted online, answering these questions also requires recording the website used and enough detail, such as a URL or navigation path, to locate the same record again.

In genealogy, citations are required for every fact that is not common knowledge. Names, dates, places, and relationships must all be supported by sources. This expectation is shared by formal genealogical institutions worldwide and applies equally to hobbyists and professionals.

Genealogical conclusions are evaluated using the Genealogical Proof Standard (GPS). One of its five mandatory elements is complete and accurate source citations. Without citations, conclusions are considered unproven regardless of how convincing they may appear.

Why Citation Is Essential in Genealogy

It allows verification: Historical records can contain errors, conflicts, or incomplete information. A citation allows anyone to return to the original source, reassess the information, and determine whether the interpretation still holds up. This is especially important for online records, where search results and database structures may change over time.

It documents research quality: Citations reveal what types of sources were consulted and how broadly a question was researched. They show whether conclusions rely on original records, derivative sources, or a mixture of both, and whether images or index-only entries were used.

It creates a research trail: A good citation acts as a roadmap for future work. It allows researchers to retrace steps, revisit archives, and build upon earlier research without repeating the same searches. Recording URLs or clear navigation paths is essential when working with online databases that do not guarantee permanent links.

It is an ethical requirement: Genealogists are expected to cite only sources they personally consulted. Citing a record that was never actually viewed creates a false research trail and misrepresents the scope of the research.

The Gold Standard: Evidence Explained

The most widely accepted guide for genealogical citation is Evidence Explained: Citing History Sources from Artifacts to Cyberspace by Elizabeth Shown Mills. This work is recommended by the Board for Certification of Genealogists and is used internationally in both training and professional practice.

Evidence Explained is valued because it goes beyond formatting rules. It teaches researchers how to analyze sources, understand how records were created, and reflect that understanding in the citation itself. Rather than relying on rigid templates, it uses flexible building blocks that can be adapted to physical records, digital images, and online databases alike.

Original Records vs Derivative Sources

A fundamental rule in genealogy is to cite what you actually used. This principle is central to both ethical practice and accurate documentation.

If you viewed an image of a certificate or register, you may cite the image and describe the original record it represents. If you only viewed an index or transcription, you must cite that index or transcription rather than the original document. This distinction becomes particularly important online, where databases may present indexes and images side by side, but only one of them was actually consulted.

When using online material, the citation should clearly indicate whether the information came from an image or an index and include enough information, such as a URL or navigation path, to locate the same material again.

Good Examples of Proper Vital Record Citations

The examples below illustrate citations that follow accepted genealogical best practices and accurately reflect the sources used.

Example 1: Physical birth certificate

Birth certificate for Anna Maria Rossi, born 14 March 1892, certificate no. 417, Comune di Firenze, Ufficio dello Stato Civile, Florence, Italy.

This citation works because it identifies the person and event, names the record type, includes the certificate number, and clearly identifies the creating agency and location.

Example 2: Digital image of a death certificate

Death certificate no. 29881 (1923) for John William Robinson, Texas State Board of Health; digital image, Texas Deaths, 1890–1976, FamilySearch (https://www.familysearch.org : accessed 21 May 2025).

This citation works because it cites the official record creator, clearly states that an image was used, and includes the website and access date so the record can be found again.

Example 3: Index entry only

Ohio Death Certificate Index, 1913–1937, database, Ohio Historical Society; entry for Eveline Powell, died 1934; accessed 3 April 2025.

This citation works because it clearly identifies the source as an index and does not imply that the original certificate was viewed. It accurately reflects what was actually consulted.

Example 4: Marriage record from a register book

Marriage of Pierre Dubois and Marie Lefèvre, 12 June 1874, Marriage Register, volume 3, page 112, Mairie de Lyon, Rhône, France.

This citation works because it identifies both parties, specifies the register, volume, and page, and names the repository.

Using Software to Manage Citations

While proper citation is a research skill, genealogy software can make consistent documentation much easier. Most modern programs support structured source citations inspired by the principles found in Evidence Explained and are designed to help researchers remain consistent across large projects.

These tools allow sources to be attached to individual facts, reused across multiple events, and clearly labeled according to whether an original record, an image, or an index was consulted. When working with online records, software also provides a place to store URLs or navigation paths alongside access dates, which is essential for long-term verification.

Common genealogy software

Online platforms such as Ancestry, MyHeritage, and FamilySearch also provide built-in citation tools. These can be helpful starting points but should always be reviewed and edited for completeness.

Common Citation Mistakes

One frequent mistake is citing records that were never actually consulted. Others include relying on auto-generated citations without review, omitting certificate numbers or repositories, or forgetting to record access dates and usable URLs or navigation paths for online sources.

These issues weaken otherwise solid research and make future verification difficult. Consistency and transparency matter more than perfect formatting, and an honest citation is always preferable to a polished but misleading one.

Key Takeaways

Proper citation is the foundation of credible genealogy and applies to every level of research, from beginner family trees to professional case studies. Citations exist to document what was used, allow verification, and support ethical research practices. You should always cite the exact source you consulted, clearly identify whether it is original or derivative, and include enough detail, including URLs or navigation paths when relevant, for others to locate it again.

You do not need to memorize complex templates to cite well. Careful observation, honest representation of sources, and consistent documentation are enough to align your work with globally accepted genealogical standards.
