I know I’ve posted about Katherine Swynford before- she even features in a chapter of Medieval Royal Mistresses. However, Kathrine by Anya Seton is one of my favourite historical novels, so the chances of me not writing about her again were slim. The novel dates from 1954 and has stood the test of time.
Katherine de Roet, the daughter of a minor Flemish knight, and her sister Philippa begin the tale as part of Philippa of Hainault’s household. It’s likely that their father came to England with the queen when she married Edward III. Philippa is married to Geoffrey Chaucer while Katherine is married to Sir Hugh Swynford, an impoverished knight from Lincolnshire. Â Seton, who is writing a novel, changes Katherine’s age to make her slightly older than she probably was in fact. What was acceptable in the fourteenth century is not something that is acceptable in modern times. A novelist can change ages – a historian has to provide the facts, and in Katherine’s case this involves potential ages and analysis of known facts both for Katherine and of known medieval averages to arrive at the most likely year for her birth and her marriage.
Swynford isn’t necessarily the most sympathetic of characters and that’s where fact and fiction part company. Quite simply we know very little about him – https://thehistoryjar.com/2017/07/14/sir-hugh-swynford/ or his relationship with Katherine. The historical record, unsurprisingly, is a blank. A novelist can fill in the blank – a historian cannot.
After Hugh’s death – and that’s where papal dispensations and account rolls provide us with historical evidence, Katherine, who is the governess to John of Gaunt’s daughters, begins an affair with the duke – although who started what is a matter of speculation rather than fact. Evidence of their relationship, explored in the non fiction work by Alison Weir, including the birth of four children, gifts, visits, monastic chronicles, court records, and the Peasant’s Revolt provide primary source evidence. The fact that Katherine married John in 1396 and that their children were subsequently legitimised provides a paper trail of evidence that would otherwise have been lacking. What makes Katherine remarkable, is that history knows as much about her as it does.
And just so we’re clear – Seton is able to develop the story of Katherine of John’s relationship because she is writing a work of fiction. The research is impeccable but while Alison Weir can only write about what the evidence provides, Seton can enhance the plot line; provide a narrative for what happened to Katherine while she was absent from the existing historical record; and use dialogue to develop character. Both writers make sound use of the sources and tell Katherine’s story but Seton does not have to rely on verifiable facts. A good historical novelist like Anya Seton does extensive research before putting pen to paper but no one should be quoting anything in a novel as historic fact, no matter how good it might be.
My favourite verifiable, historical fact is that on Valentine’s Day 1382, Gaunt issued Katherine with a legal document which said that neither of them owed each other anything. It was a formal renunciation of property rights. The quitclaim, to give the document its correct name, ended their ten year old affair. No one could now take away from Katherine anything that the duke had given to her. She was independent and safe. It’s an unusual Valentine – but John of Gaunt was a hated figure at this time. The Peasant’s Revolt of the previous year had seen his London residence at The Savoy burned to the ground. The Church was attacking him because of the protection he offered to John Wycliffe. Monastic chroniclers attacked Katherine in order to damage the duke. There was also the small matter of Gaunt’s second wife, Constanza of Castile and Gaunt’s desire to win himself a crown of his own.
And if you like to compare writers – Anne O’Brien’s The Scandalous Duchess is also about Katherine Swynford.













Today we have arrived at the third surviving son of Edward III – John of Gaunt, Duke of Lancaster. Â I’ve posted about him before so I don’t intend to write about him in any great detail here – but there is a very tangled Plantagenet skein to unravel in terms of his children.
During the latter part of the 1350s Edward III was looking to provide wealth and land for his older sons. Blanche married John of Gaunt at Reading Abbey in May 1359. Â Blanche gave birth to seven children between 1360 and her death in 1368 but only three survived to adulthood: Philippa, Elizabeth and Henry of Bolingbroke. Philippa married into the royal house of Portugal in 1387 as part of the Treaty of Windsor so for the time being we can remove her from the intersecting Plantagenet lines – possibly with a huge sigh of relief.

Thomas Walsingham was a Benedictine monk.  He lived at St Albans Abbey where he had been educated and is usually considered the last of the great medieval chroniclers being a prolific producer of manuscripts including the “Chronicon Angliae” which covering the years 1328 to 1388.  It is in this chronicle that he criticises John of Gaunt.  The “Gesta Abbatum” or the St Albans Chronicle or Chronica Maiora as a continuation of that of Mathew Paris – and in fact his histories draw heavily on Paris’s work. His writings end in 1422 when he died but it is from Walsingham that we know about Wat Tyler, John Wycliff and the reigns of Richard II and Henry IV.
Rather amusingly and to the detriment of the chronicle a second version was penned after Henry IV, who was of course Gaunt’s son, came to the throne. Oddly all the unpleasant remarks about Gaunt were removed…so that the first version came to be known as “the scandalous chronicle.”
It was quite common in the earlier part of the Middle Ages for a parent to dedicate a baby or a young child to holy orders. Â These children were called oblates because the child was offered to God with an altar cloth wrapped around their right hand – an oblation or offering.
