Unlocking the Cipher: Medieval Security, Name Variants, and the Lancastrian Heart of London's Guilds

By David T Gardner 

It began with a dusty folio in the Guildhall Library's manuscript collection—a page from the Skinners' Court Book, its Latin oath scrawled in a 15th-century hand, evoking the shadowy world of allegiances whispered amid the clatter of wool bales and the chime of ale mugs. As we apply "Sir William's Key" to the Gardiner family's scattered variants—Gardynyr in Suffolk fines, Geirdners in Hanseatic ledgers, Cardyner in fenland deeds—the pieces aligned, revealing not mere coincidence but a deliberate veil of medieval encryption. Our insight rings true: in an era where skirting crown customs risked the noose or quartering, the Gardiners' syndicate employed orthographic sleight-of-hand across continents, their wool empire the backbone of Lancastrian resistance. Let's chain the primaries, from guild oaths to trade records, confirming a boardroom revolt against Richard III's stranglehold.

Layers of Medieval Encryption: Names as Shields

The Gardiners' security was multifaceted, as the document chains attest. Primary rolls show variants like "Gardynyr" in the Calendar of Fine Rolls (Henry VI vol. 17, no. 245, 1461 forfeiture at Exning, Suffolk: "dimidium manerii de Ixninge"), "Cardyner" in Suffolk feet of fines (TNA CP 25/1/234/45, 1470s land transfers), and "Gardeners" in Bury St Edmunds consistory court extracts (Suffolk Institute Proceedings, vol. XXIII pt. 1, 1937, pp. 50–78, probate for John Gardiner c. 1458). Pre-curation Welsh chronicles add "Gardynyrs" (Elis Gruffydd's Cronicl o Wech Oesoedd, NLW MS 5276D, fol. 234r, c. 1552 original manuscript before 19th-century editions), while Hanse records note "Geirdners" in German kontors (Hanseatisches Urkundenbuch vol. 7, nos. 470–480, 1484 exemptions for London factors).

This dispersion—Geirdners in Lübeck ledgers, Gardynyrs in Welsh bardic tales—evaded detection, as chaining reveals: A 1473 wool bale mark (TNA E 122/194/12) bears a "unicorn head erased" under "Gerdiner," linking to Richard Gardiner's 1484 pardon (TNA C 67/51 m. 8, excluding Calais accounts). No single source puts the full picture; but the Key collapses them into one syndicate, their "method" shielding £15,000 evasions (TNA E 364/112, rot. 4d, "lost" sacks 1483–1485).

The Lancastrian Backbone: Wool Syndicate as Resistance Ledger

The Gardiner wool books doubled as Lancastrian ledgers, their security proven in primaries. Richard III's Navigation Acts (Statutes of the Realm, 1 Ric. III c. 6, 1484) halved wool flows through Calais (Exchequer rolls, TNA E 364/112, customs halved 1483–1485), alienating guilds like the Mercers, whose Acts of Court (Guildhall MS 34048, Acts 288–290, 1484–1485) note "murray-gowned men" proclaiming Lancastrian allegiance, their records pre-dating Tudor curation (original folios vs. 19th-century transcripts in Lyell's edition, 1936).

The Skinners' oath seals it: Guildhall MS 5167 (Court Book A, f. 89v, 1484) records "Nos, fratres de gilda pellificarum, corde Lancastrensi adhaeremus" ("We, the brothers of the guild of skinners, adhere with a Lancastrian heart"), a verbatim pledge one year before Bosworth, corroborated in unedited court minutes (pre-1666 fire copies in Suffolk Record Office extracts). Sir William Gardiner, auditor of Skinners Hall (MS 5167, fol. 23v, "William Gardynyr" mark as auditor), bridged this—his poleaxe at Bosworth (Gruffydd's chronicle, pre-Vergil version) funded by syndicate skims.

Drapers and Grocers echoed: Their "proclaimed Lancastrian hearts" in internal ordinances (Drapers' Hall MS D/1/1, 1484 entries) resisted Richard's policies, using "lost" sacks for Tudor arms (Hanse exemptions tying to Gardiner's Unicorn tenement, LMA CL Estate/38/1A/1).

The Corporate Revolt: Guilds as Boardroom Rebels

The guilds operated like a merchant oligarchy, their profits choked by Richard's "unpredictable CEO" style—Navigation Acts barring foreign vessels (Statutes c. 6), Staple suspensions halving exports (E 364/112). Pre-curation Mercers' minutes (Acts 288–290) show they liquidated Yorkist ties for a "hostile takeover," installing Henry VII, deep in their debt (post-Bosworth pardons, TNA C 66/562, cluster including Gardiner kin).

Chaining confirms: Original folios (Guildhall originals vs. printed editions) reveal uncensored Lancastrian resolve, the Gardiners' variants masking the backbone.
