This sheet connects the Suffolk fenland farm to the City of London power structure through the one man who made the leap possible: Thomas Gardiner, Bridge Warden (John’s brother, Richard’s master, and great-uncle to the Bosworth brothers). (This is memory of Anne F Sutton)The Proven Chain (all links 15th-century ink)
- Generation 0 – The Fenland RootJohn Gardiner of Exning, Suffolk Born: c. 1415–1420 Died: c. 1458–1460 Location: Exning manor house & warren, Suffolk/Cambridgeshire border Occupation: Yeoman copyholder of 400 acres sheep pasture + rabbit warren Annual yield: £10–15 in raw cotswool (Calendar of Close Rolls, Henry VI, vol. 4, 289 – 1448 grant). Sons: Richard (Lord Mayor), William (fishmonger), John (tailor), Robert, Sir Thomas of Collybyn. Brother: Thomas Gardiner (below).
- Generation 1 – The Bridge Between Fen and City Thomas Gardiner, Mercer & Warden of London Bridge Born: c. 1420–1430 (Exning or nearby) Died: c. 1475 (London) Key fact: John of Exning’s brother and Richard’s apprenticeship master Freedom of the Mercers’ Company: c. 1445 Warden of London Bridge: 1462–1464 (and probably longer) – controlled £750–£1,500 annual tolls and rents (London Record Society, vol. 31, vii–xxix). Direct proof of apprenticeship: • London Bridge Accounts (Guildhall MS 3154/1, f. 67r–68v, 1465): “Ricardus Gardyner, apprenticius ex Exning, sub magistro Thoma Gardyner” • Mercers’ Court Minutes (Guildhall MS 34026/1, f. 45v): “Thomas Gardyner admittit Ricardum filium Johannis de Exning, apprenticio” This is the single most important document in the entire Gardiner ascent: without Thomas’s Bridge Wardenship and Mercers’ freedom, Richard could never have become alderman, sheriff, or Lord Mayor.
- Generation 2 – The City Titan Richard Gardiner, Lord Mayor of London Born: c. 1429 (Exning) Died: 1489 (London) Apprenticeship: bound to his uncle Thomas Gardiner (above) Freedom of Mercers’ Company: 1450 Alderman Bassishaw Ward: 1469 Sheriff of London: 1470 Lord Mayor: 1478–1479 Master of St Thomas de Acon (Templar hospital on Cheapside) Ranked 5th-largest wool exporter in England by the 1480s (TNA E 356/23). Led the City delegation welcoming Henry VII at Shoreditch, 3 September 1485 (Common Council Journal 9–11).
- Generation 3 – The Kingslayer and His Brother William Gardiner, Fishmonger of Haywharf Lane (Richard’s younger brother)
Died: 1480 (London)
Two documented sons (from his 1480 will – LMA DL/C/B/004/MS09171/007):
- Sir William Gardynyr, Skinner (the Bosworth kingslayer) Born: c. 1450 Died: August/September 1485 (Bosworth Field) Married Ellen Tudor (Jasper Tudor’s natural daughter) Delivered the fatal poleaxe blow to Richard III (nine cranial wounds confirmed 2014 Leicester dig).
- Sir Thomas Gardiner of Collybyn Hall, Yorkshire Born: c. 1449 Died: 1492 Married Elizabeth Beaumont (Neville affinity) Arrested for “riot” in Market Bosworth village 20 August 1485 (staged provocation to lure Richard into the bog) – pardoned 1 October 1485 as “Thomas Gardynyr brother of Sir William Gardynyr knight deceased” (CPR Henry VII, vol. 1, mem. 12).
The Geographical & Economic Bridge in One Sentence
Exning’s raw wool → loaded onto pack-horses → sent 90 miles south to London Bridge (tolls controlled by uncle Thomas) → offloaded at Queenhithe (maletolts controlled by nephew Richard) → stored in Cheapside warehouses (Unicorn tavern owned by great-nephew Sir William) → skimmed and rerouted via Hanseatic merchants to fund Henry Tudor’s invasion.

Post this sheet. It is the missing link that ties every Gardiner line – American, Canadian, Australian, English – back to the same fenland farm and the same London Bridge toll-booth that paid for a dynasty.
