Corresponded with

Letters between these two correspondents, counted only when both sender and recipient were read from the letter itself. This does not imply agreement or affinity.

Shared letters divided by the smaller of the two correspondents' totals of letters sent and received. 0 of 1 correspondents meet the floor of 5 letters. Those rows are ordered by overlap, then count, then name; rows below the floor follow by count, then name.

About this index

Dataset and reviewed rules

Tier 1: derived from the published letters index, the reviewed correspondent groups and the reviewed place list by the rules below — no inference, no model. Post-fold (sitting 2026-09-05): 169 reviewed correspondent groups; 2090 printed forms remain groups of one below the review floor, disclosed. Corpus version 5db27b8755bd; 170 records. Weighting constants: PROVISIONAL — the EC sitting's constants (2026-08-30) reused pending the Douglass correspondence sitting; changed only by a sitting. raw count everywhere — the count is the fact; ordering is presentation.

Identities: 172 of the 2,262 names in this layer are reviewed groupings. A name marked “as printed” is a form no ruling has reached — it may be one person, several, or part of another identity; an unmarked name is a reviewed identity.

Names and terms in the same records

Rule: vocabulary term (aliases OR-folded) × correspondent, FOLDER-level co-occurrence: the term's whole-word hit on a folder text × the person's letters in that folder — never letter-level (letter boundaries are not delimited beyond the anchors)

Order: distinctive first (lift)records * N / (deg_term * deg_person); N = total fts records; degrees = graph_term_records / graph_person_records counts; support floor 5.

On this page: Order is “distinctive first” above the reviewed floor of 5 records, then by count.

SELECT t.slug FROM graph_term_records t JOIN graph_person_records p ON p.slug = t.slug WHERE t.term = :term AND p.person = :person ORDER BY t.slug

Rule: letters carrying both parties (the boundary sentence), grouped by the unordered pair of correspondent groups; see the builder A correspondence is counted only where both a sender and a recipient were read from the letter itself; letters with one party read are in no edge.

Correspondence weighting: Shared letters divided by the smaller of the two correspondents' totals of letters sent and received. Support floor 5. provisional; the EC alongside floor reused as the correspondence floor.

SELECT id FROM letters WHERE (sender_group = :person_a AND recipient_group = :person_b) OR (sender_group = :person_b AND recipient_group = :person_a) ORDER BY year, id

How these results are ranked

Distinctiveness (lift) compares how often a term and a name share records with the frequency expected from their separate record totals. It is not evidence of personal interest or influence.
