1 The search ‘how many medieval women died in childbirth’ brings up a variety of blogs, articles and essays that characterise the reproductive experience as incredibly dangerous, though hard evidence to support these claims proves elusive. Sara Bryson's article in Tudor Society asserts that one in three women died during their fertile years (Sara Bryson, ‘Childbirth in Medieval and Tudor Times’, The Tudor Society, https://www.tudorsociety.com/childbirth-in-medieval-and-tudor-times-by-sarah-bryson/ [accessed 28 March 2018]. Another blog that appears as a top result, Medieval Woman, asserts that ‘many women suffered greatly and many more died in childbirth … [there was] little to relieve the stresses of childbirth other than poultices and prayer’; (Rosalie Gilbert, ‘Medieval births and birthing’, Rosalie's Medieval Woman, https://rosaliegilbert.com/births.html [accessed 28 March 2018]). Bryson cites four videos and one book, In bed with the Tudors, while the Medieval Woman entry lacks footnotes entirely.

2 Walden Abbey's monastic history, ‘Fundationis Historia’, transcribed in Dugdale (Monasticon Anglicanum: A history of abbies and other monasteries, hospitals, frieries, and cathedral and collegiate churches, 2nd edn (London, 1823), Vol. IV, 139) records the children of Humphrey with ‘Elizabethae illustris regis Angliae Edwardi’ as follows: ‘Margareta primogenital sua, apud Tinehmue sibi fuit nata; apud Knaresburgh, Humfridus filius suus primogenitus; apud Plesset, Johannes; apud Longmaban in Scotia, Humfridus; apud Caldecot, duo gemili nobiles, Edwardus et Willelmus; apud [illegible], Eneas; et apud quenden, quaedam filia de qua praedicta nobilis domina Elizabetha comitissa in puerperio mortua apud Walden sepulta est’. The exact date of her death is also noted in her psalter, British Library Add MS 24686 f.7r.

Benedictow asserts that lowered female immune reactivity due to reproductive stress led to female supermortality during the Black Death. He further posits that the gendered division of labour led to increased exposure to illnesses for women.

5 The skeletal assemblage at the Anglo-Saxon cemetery of Raunds Furnell, for example, indicated that by the age of 35, only 29 per cent of women would still be alive compared to 54 per cent of men. See Andy Boddington et al., Raunds Furnells: The Anglo-Saxon church and churchyard, English Heritage Report 7 (Swindon, 1996), 30. Sayer and Dickinson's survey of Anglo-Saxon burials posits that up to 50 per cent of young female fatalities in the Anglo-Saxon kingdoms may have been cases of maternal mortality. See Sayer, and Dickinson, , ‘Reconsidering obstetric death and female fertility in Anglo-Saxon England’, World Archaeology 45, 2 (2013), 286CrossRefGoogle Scholar. This trend continued into the later medieval period: mortality among women interred in several cemeteries in the medieval cemetery of York also peaked between the ages of 25 and 35. Grauer, Anne L., ‘Where were the women?’, in Herring, D. Ann and Swedlund, Alan C. eds., Human biologists in the archives: demography, health, nutrition and genetics in historical populations (Cambridge, 2003), 277Google Scholar. In the recent literature, however, bioarchaeologists have proposed that this peak in female mortality between the ages of 25 and 35 is due to the linear progressions used to assess age-at-death and may not be reflective of historical reality. An alternative method using Bayesian statistics may alter the clustering of deaths between 25 and 35, though at present a reassessment of the medieval data is lacking. For an overview of the debate on determining age-at-death and the use of Bayesian prediction, see Rogers, Tracy L., ‘Skeletal age estimation’, in Blau, Soren and Ubelaker, Douglas H. eds., Handbook of forensic anthropology and archaeology (Walnut Creek, 2009), 209–11Google Scholar.

6 The data were downloaded from Roberta Gilchrist and Barney Sloane's ‘Medieval monastic cemeteries of Britain (1050–1600): a digital resource and database of excavated samples [XCLM76, XMAB85; XSME65]’, (York, 2005), doi: 10.5284/1000273 [accessed 25 March 2019]. The three nunneries analysed are the Benedictine nunnery of St. Clement, York, the Benedictine nunnery of St. Mary Nunnaminster, Winchester, and the Benedictine nunnery of St. Mary at Elstow, Bedfordshire. They were selected for their sample size, and because they were neither hospitals nor Black Death cemeteries. Excavations resulted in a total of 162 female skeletons. Excluding the 3 for which no age at death could be determined, and the 31 categorized as ‘general adults’ results in a sample of 128 female skeletons for whom age at death could be determined. Of these, 88 (68 per cent) were between the ages of 26 and 45 at death. I would like to thank Sandy Bardsley for alerting me to this resource.

Marilyn Oliva determined that the average age of nuns in the diocese of Norwich was 43 in the fourteenth century and 32 at the Dissolution; Oliva used 15 as the average age of entry and 16 as age of profession. See Marilyn Oliva, The convent and the community in late medieval England: female monasteries in the diocese of Norwich, 1350–1540 (Rochester, 1998), 46. In a more recent study of the necrology of the nuns of St. Agnes in Gorinchem, Holland, Jaco Zuijderduijn found that life expectancy decreased over the course of the fifteenth century, from 67.5 years in the first 25 years of the convent's existence to 41.6 in from 1505 to 1529. When compared to life expectancy in three male houses in England (Durham, Canterbury and Westminster), the sisters of St. Agnes fared much better, at least until the end of the fifteenth century, when life expectancy at Durham and Westminster surpassed that of Gorinchem. Prior to this, however, the crude average death rate of Gorinchem was much lower than that reported for either professional religious or secular members of English society. Zuijderduijn concludes that mortality in England was relatively high when compared to that experienced in Holland, perhaps because England was generally a less salubrious society.

See pp. 23–4 for references to the reports including these cases.

16 Children's bodies skeletonize faster and are more prone to disarticulation by scavengers, and their crania are easily damaged during excavation. The burial practices employed may also complicate recovery of infant remains; for example, at Watchfield cemetery, Oxfordshire and Chantambre, France, the graves of children were much shallower, increasing the risk of damage and dispersal.

The authors calculate a Maternal Mortality Rate (MMR) of 14.4 per 1,000. They ultimately conclude that roughly one in five Florentine women would die due to risks associated with childbearing.

22 1236 was chosen as an appropriate starting date because the queen before Eleanor of Provence, Isabella of Angoulême, married Hugh X de Lusignan after the death of her first husband, King John, moving her beyond the geographic focus of this study, which is primarily interested in England. 1503 acts as an effective terminal date because it marks the beginning of a period of change in the reproductive experiences of English royalty, and of their utility for this analysis; Anne Boleyn and Catherine Howard were executed prior to completing their reproductive lives, and Anne of Cleves’ marriage was declared unconsummated after six months. The experiences of Henry's children are also limited for the purposes of this survey, as only Mary wed.

25 It is likely that pregnancies which resulted in miscarriages, stillbirths or short-lived children never entered into the documentary record and were therefore missed during the process of data entry. Sex ratios, however, offer a rough method for evaluating the completeness of the evidentiary assemblage. Worldwide, the sex ratio at birth is about 107 males born per 100 females; the ratio balances over time, as the immune system of females is generally hardier and more effective than those of their male counterparts. Of the BADE pregnancies, 446 (97 per cent) resulted in children of determinate sex, leading to a male:female ratio of 223:220, or 101:100. It seems, therefore, that some pregnancies resulting in male infants are missing from the evidence base, though if we take the number of pregnancies resulting in female children as accurate, the 223 male-resulting pregnancies represent 95% of the total number expected. This lacuna might be due to a lack of documentation, or because pregnancies which would have resulted in male children ended too early for observers to note the child's sex. The latter explanation, miscarriage, is discussed more fully below.

She was able to gather information on about 1,200 aristocratic couples and their children. Because her goal did not include recording maternal age at delivery or date of birth; however, her sample size is much larger than my own, which is limited by the relative rarity of accurate recording of birth dates for both mother and child. There is some overlap in the two evidentiary assemblages, though Harris's work excludes royal women and members of the gentry who did not marry into a knightly family.

68 For royalty in particular, the exact date of birth (day, month and year) was recorded in primary source material. These cases were in the minority, however, and for many entries in BADE only year and month (105 cases) or only year (352) were recorded. Of the 75 birth events lacking sufficient information for dating, over half were births to gentry women. For this reason, the interval analysis includes only dateable birth events and intervals are reflected in years.

69 Manuals of the time, including Bartholomaeus Anglicus's De proprietatibus rerum (c. 1230) and The Byrth of Mankynd (c. 1540) advocated for mothers to feed their own children, but also provided considerable detail on how to select a wet nurse, testifying to the continued popularity of the practice. See Valerie Fildes, Wet nursing: a history from antiquity to the present (Oxford, 1988), 33–42. Jennifer Ward (Women in England in the Middle Ages (New York, 2006), 52–3) discusses the role of wet-nurses among the English elite, noting that the practice was common after the Anglo-Saxon period. Records of payments for their services and letters from distant parents inquiring after their children testify to the continued practice through the end of the middle ages.

84 Ibid., 203–7. Tomkins’ survey of Shropshire midwife books includes several records which recorded stillbirths as well as live births. The man-midwife Thomas Higgins, for example, delivered 1,196 infants during 1781–1803, including 1,140 live births, 47 stillbirths and 9 miscarriages. Two of the other midwives studied, John Greene and Frances Johnson, recorded maternal burials, baptisms and miscarriages, but not stillbirths.

85 J. C. Parsons, ‘The year of Eleanor of Castile's birth and her children by Edward I’, Mediaeval Studies 46, (1984), 256–7, 263. Parsons notes that Eleanor usually spent 40 days confined after the birth of a son, but only 30 after giving birth to a daughter. This contrasts with her mother-in-law, Eleanor of Provence, whose lying ins lasted 40 days regardless of the sex of the child.

86 Lewis, ‘Maternal health’, 101. For this study, Lewis identified 48 aristocratic Englishwomen, c. 1790–1894, whose childbearing experiences could be effectively reconstructed through surviving correspondence and journals.

87 Tomkins, ‘Demography’, 219–20. Tomkins also notes that the English rate is high compared to that observable in similar Swedish evidence, which was 28 stillbirths per 1,000 live births.

Among the 48 women analysed by Lewis (‘Maternal health’, 99), the average age at first pregnancy was 20, the same as in the BADE sample. Lewis's early modern aristocratic women, however, continued bearing children long after most of the medieval cohort had ceased; in her sample, the mean age at last pregnancy of 39.3 years. Harris (English aristocratic women) does not include any information on average age at first or last pregnancy.

95 253 birth events (55.4 per cent) had no risk factors; 51 (11.2 per cent) had two risk factors, and 9 (2 per cent) had three risk factors.

96 They were Mary de Bohun, Elizabeth of York, Elizabeth of Rhuddlan, Eleanor Holland, Anne Mortimer and Margaret of Scotland.

97 Lewis, ‘Tis a Misfortune’, 33. Table 2, ‘Maternal mortality by 50-year birth cohorts’, shows a peak between 1750 and 1799, with a total of 8 per cent of the 225 women dying in childbirth. In 1850–1899, a dramatic drop occurs, with only 2 out of 222 women dying due to childbirth.

98 Ibid., 34. Unfortunately Table 3 of Lewis's article recording maternal deaths per 1,000 live births is not broken down any further than ‘Before 1700’, ‘1700–1799’ and ‘1800–1899’.

99 Dr. Thomas Denman, for example, wrote that ‘the lower orders of women have more easy and favourable births than those who live in affluence’; Thomas Denman, An introduction to the practice of midwifery (Brattleborough, 1807), 188. Dr. William Buchan similarly observed that ‘inhabitants of every country are prolific in proportion to their poverty’; William Buchan, Domestic medicine: or, a treatise on the prevention and cure of diseases by regimen and simple medicine (Philadelphia, 1772), 340.

104 This is not a new conclusion. Even Dr. Buchan, writing in the 1760's, noted that though poor women seemed to have an easier time getting pregnant, they suffered more: ‘poor women, whose circumstances oblige them to quit their bed too soon, often contract diseases from cold, of which they never recover’; Buchan, Domestic medicine, 339.
