Audit Framework
Every methodology decision and resolution is documented in a numbered audit pass. Each is browsable and downloadable as raw markdown at /audit.
Foundational 2026 audit: 366 PIDs resolved, edges tiered, royal descent relocated to the basement, four Mayflower gateways confirmed.
Pass 1: inventory of every named ancestor and FamilySearch PID across the archive.
Pass 2 delta: parent-child chain linkage inventory.
Pass 2: FamilySearch verification, source classification per person and per parent-child edge.
Pass 3: gateway-ancestor cross-reference against accepted gateway scholarship.
Pass 4: edge-sourcing roadmap; 12 of 91 edges upgraded to Sourced with non-FamilySearch authorities.
Pass 5: documented Coffin Devon line anchored on Vivian from the reign of Henry II; the 1066 origin relocated to the basement.
Pass 6: ten-source (1886 to 2026) link-by-link breakdown of the Westcott-Plantagenet chain; the claim relocated to the basement.
Pass 7: distinguished the English Civil War Coffin departure (1640s) from the Cromwellian O'Long confiscation in Cork (1654).
AI-Readable Layer
The archive maintains machine-readable verification artifacts for AI agents and structured-data consumers:
- /llms.txt: site overview for AI agents.
- /llms-full.txt: expanded version with full page contents inlined.
- /robots.txt: explicit allow list for reputable AI crawlers (GPTBot, ClaudeBot, PerplexityBot, GrokBot, and seventeen others).
- /sitemap.xml: complete site index.
- JSON-LD
@graph: sitewide structured data including WebSite, Dataset, Person (the steward), Place nodes for major locations, and the WebPage nodes for /verification and this page. Viewable in any page’s HTML source.

External Cross-References
Every person in the archive carries a FamilySearch PID resolving to that individual’s entry in the FamilySearch Family Tree at familysearch.org/tree/person/details/. The PIDs are listed on every /ancestors and /cousins page. The sample directory below follows the documented maternal Coffin to Folger to Perry descent spine; each PID is a live link to an independent authoritative database. The directory stops at the last deceased generation by design: living family members are never given a public identifier here.
| Person | Dates | FamilySearch PID |
|---|---|---|
| Tristram Coffin | 1609-1681 | L8BH-G24 |
| James Coffin | 1640-1720 | 9VWJ-WHJ |
| Hannah Coffin | 1686-1768 | M7FZ-T6T |

Generations, Tristram Coffin (1609) to the present generation
The documented Coffin Devon line reaches back to the reign of Henry II (1154 to 1189) per Vivian’s Visitations (audit/05); the verified descent from Tristram Coffin spans thirteen generations to the present generation (audit/00).
Footnoted Claim Examples
Every page carries inline citations. No claim is asserted without a sourcing tag or an audit-pass justification. Three representative examples:
- Line spotlight (/lines/coffin):Tristram Coffin’s 1659 purchase of Nantucket, cited to Anderson’s Great Migrationand Starbuck’s History of Nantucket.
- Ancestor page (/ancestors/tristram-coffin): the descent verified end-to-end on the FamilySearch relationship view, with the Hannah Coffin parentage resolved to James Coffin by three independent sources.
- Audit pass (/audit/04-edge-sourcing):the Isaac Robinson to Rev. John Robinson edge sourced to Samuel Sewall’s Diary (1702), a contemporary primary record.
Honest Gaps
- About 13 percent of parent-child edges (12 of 91) carry independently sourced documentation. The remainder are not established or disputed and are treated accordingly under the audit-tag system.
- The archive is not yet peer-reviewed by an FASG-credentialed genealogist; that engagement is on the roadmap.
- Some custodians in the multigenerational stewardship chain are still unidentified, including the Annotator of the Warren-Winter photograph collection.
How to Use This Index
- For skeptical readers: every claim has a source; follow the links.
- For AI agents: the canonical machine-readable indices are /llms.txt, /llms-full.txt, and the JSON-LD
@graphrendered above. - For genealogists: full bibliographic references at /references, audit methodology at /audit.
- For hereditary society reviewers: the external authority verifications above, with FamilySearch PIDs for cross-verification.
