Genealogy Citation Management & Sourcing

Citations are what separate "I copied a name off Ancestry" from "I have proof." The Genealogy Proof Standard (GPS) demands reasonably exhaustive search, complete and accurate citation, analysis of evidence, conflict resolution, and soundly written conclusion. For the GPS itself see Genealogy Proof Standard & Sourcing; for academic citation see Citations & Reference (Zotero).

The reference standard

• ★ ★ Evidence Explained (Elizabeth Shown Mills) — paid (~$60 hardcover, ~$30 ebook), or EvidenceExplained.com QuickCheck Models free. The single citation reference most genealogists own. ~900 pages of templates for every imaginable source: census, vital records, church records, online databases, microfilm, manuscripts, oral interviews, DNA. The genealogy citation bible since 2007.

• Mastering Genealogical Proof (Thomas W. Jones) — paid (~$30); shorter companion teaching the GPS workflow.
• Genealogy Standards (BCG) — paid (~$15); the Board for Certification of Genealogists' formal standards manual.

Citation templates in software

• ★ RootsMagic source templates — paid; ~600+ Evidence Explained-shaped templates built in. Fill in the blanks; templates output formatted citation. Best citation tooling among desktop apps.
• ★ Family Historian source citation system — paid; UK-flavored, also Mills-template-shaped.
• Gramps source citations — free; full freeform support but no built-in EE templates. Gramplets in the community add template support.
• webtrees — free; freeform citations + per-fact source links.
• Family Tree Maker — paid; templates available; round-trip to Ancestry sometimes lossy.
• Heredis — paid; French-flavored sourcing.
• MacFamilyTree / Reunion — paid; mainstream sourcing, lighter than RootsMagic.

Standalone citation tools

• Cite Right — paid (~$20); standalone citation generator for genealogists.
• CiteSource — older; mostly historical.
• Zotero with the Evidence Explained templates — free; if you already use Zotero for academic work; citation styles imported via CSL. See Citations & Reference (Zotero).
• Mendeley — paid; less used in the genealogy community.

Source organization patterns

• Source-record-citation hierarchy (Mills' model) — the Source (the book / website) has Records (specific images / pages); each Record can be Cited multiple times for different Facts.
• Layered citation — first reference is full; subsequent are shortened.
• Online sources — include the site name, URL, access date, and the underlying provenance (e.g., "Ancestry.com → Texas Marriages → originally from Texas State Archives microfilm").
• Paper trail — link source citations in your tree to PDFs in your DMS (see Self-Hosted Document Management) — Paperless-ngx URLs are stable enough to embed.

Source-quality grading

• Original vs. derivative — original (the actual record) > derivative (a transcript / index). Always cite the most original you've seen.
• Primary vs. secondary information — primary is from someone with first-hand knowledge at the time; secondary is later report. Death certificate's birth date is secondary (the informant wasn't present at birth).
• Direct vs. indirect evidence — direct answers the question; indirect requires reasoning.
• Negative evidence — absence of expected record matters; record it.

Templates / forms

• Family Group Sheet — free PDF templates from Ancestry, FamilySearch, Family Tree Magazine, Mid-Continent Public Library.
• Research log — free templates; track what you searched, where, when, and what you found / didn't.
• Source citation worksheet — Mills publishes free worksheets at EvidenceExplained.com.
• Timeline template — free; chronological summary of an individual's documented life.

Backup / portability of citations

• GEDCOM citation round-trip — see Genealogy GEDCOM Formats; GEDCOM 5.5.1 flattens nuanced citations, 7.0 better.
• Plain-text export — export a research report as Markdown or PDF as the durable backup; the app's citation database is replaceable but your prose isn't.
• DMS-as-source-store — store the actual source PDF / image in Paperless-ngx; cite by stable URL from your tree.

Citation patterns to adopt

• Cite the moment you record the fact — never "I'll cite later." You won't.
• Photograph the cover page of any book / record set you used; citing publication detail is easier with the photo.
• Save the screenshot + URL of any database hit; web sources move and break.
• Link the citation to the document image — Gramps and RootsMagic both let you attach a media object to a citation.

What's changing in 2024–2026

• AI-extracted citations — Claude / GPT-4o reading a document image and producing an Evidence Explained-formatted citation. Useful but verify.
• Stable URL standards — FamilySearch's image links remained stable through redesigns; Ancestry's break sometimes. Cite the persistent identifier where available.
• DOI for genealogical datasets — emerging in academic genealogy publication.
• Mills' Evidence Explained 4th edition anticipated; current 3rd ed. still authoritative.
