Scurvy in the Great Irish Famine: evidence of vitamin C deficiency from a mid-19th century skeletal population.

Scurvy has increasingly been recognized in archaeological populations since the 1980s but this study represents the first examination of the paleopathological findings of scurvy in a known famine population. The Great Famine (1845–1852) was a watershed in Irish history and resulted in the death of one million people and the mass emigration of just as many. It was initiated by a blight which completely wiped out the potato—virtually the only source of food for the poor of Ireland. This led to mass starvation and a widespread occurrence of infectious and metabolic diseases. A recent discovery of 970 human skeletons from mass burials dating to the height of the famine in Kilkenny City (1847–1851) provided an opportunity to study the skeletal manifestations of scurvy—a disease that became widespread at this time due to the sudden lack of Vitamin C which had previously almost exclusively been provided by the potato. A three-scale diagnostic reliance approach has been employed as a statistical aid for diagnosing the disease in the population. A biocultural approach was adopted to enable the findings to be contextualized and the etiology and impact of the disease explored. The results indicate that scurvy indirectly influenced famine-induced mortality. A sex and stature bias is evident among adults in which males and taller individuals displayed statistically significantly higher levels of scorbutic lesions. The findings have also suggested that new bone formation at the foramen rotundum is a diagnostic criterion for the paleopathological identification of scurvy, particularly among juveniles.

Victims and survivors: Stable isotopes used to identify migrants from the Great Irish Famine to 19th century London

Historical evidence documents mass migration from Ireland to London during the period of the Great Irish Famine of 1845-52. The rural Irish were reliant on a restricted diet based on potatoes but maize, a C(4) plant, was imported from the United States of America in 1846-47 to mitigate against Famine. In London, Irish migrants joined a population with a more varied diet. To investigate and characterize their diet, carbon and nitrogen isotope ratios were obtained from bone collagen of 119 and hair keratin of six individuals from Lukin Street cemetery, Tower Hamlets (1843-54), and bone collagen of 20 individuals from the cemetery at Kilkenny Union Workhouse in Ireland (1847-51). A comparison of the results with other contemporaneous English populations suggests that Londoners may have elevated δ(15) N compared with their contemporaries in other cities. In comparison, the Irish group have lower δ(15) N. Hair analysis combined with bone collagen allows the reconstruction of perimortem dietary changes. Three children aged 5-15 years from Kilkenny have bone collagen δ(13) C values that indicate consumption of maize (C(4)). As maize was only imported into Ireland in quantity from late 1846 and 1847, these results demonstrate relatively rapid bone collagen turnover in children and highlight the importance of age-related bone turnover rates, and the impact the age of the individual can have on studies of short-term dietary change or recent migration. Stable light isotope data in this study are consistent with the epigraphic and documentary evidence for the presence of migrants within the London cemetery.

Skeletal manifestations of stress in child victims of the Great Irish Famine (1845–1852): Prevalence of enamel hypoplasia, Harris lines, and growth retardation

The Great Irish Famine of 1845-1852 is among the worst food crises in human history. While numerous aspects of this period have been studied by generations of scholars, relatively little attention has so far been given to the physiological impact it is likely to have had on the people who suffered and succumbed to it. This study examines the prevalence of enamel hypoplasia, Harris lines, and growth retardation in the nonadult proportion of a skeletal population comprising victims of the Famine who died in the workhouse in the city of Kilkenny between 1847 and 1851. The frequency of enamel hypoplasia in these children does not appear to have increased as a consequence of famine, although this fact is likely to be a reflection of the osteological paradox. Harris lines and growth retardation; however, were very prevalent, and the manifestation and age-specific distribution of these may be indicators of the Famine experience. While there was no clear correlation in the occurrence of the assessed markers, the presence of cribra orbitalia displayed a significant relationship to enamel hypoplasia in 1- to 5-year-old children. While starvation, metabolic disorders and infectious diseases are likely to have greatly contributed to the manifestation of the markers, the psychosocial stress relating to institutionalization in the workhouse should not be underestimated as a substantial causative factor for skeletal stress in this population.

‘Children in a Ragged State’: Seeking a Biocultural Narrative of a Workhouse Childhood in Ireland during the Great Famine (1845–1852)

Despite the fact that more than half of all who died in the Great Famine in Ireland from 1845 to 1852 were children, relatively little research has focused on their experiences of this period. Following the archaeological excavation of a Famine-period workhouse mass burial ground in Kilkenny City, the physical reality of the catastrophe for over 500 of its child victims has become evident. The experience of poverty, famine and institutionalization can be discerned from markers of stress in their skeletons and, when discussed in a biocultural research setting, these markers provide a unique insight into the tragic veracity of one of the worst subsistence crises in history. The historical records reveal that amongst high child mortality rates, the well-being of the children was in fact a priority for workhouse officials. Though many died, a large number of childrens lives would also have been saved in the institution.

Mortality among institutionalised children during the Great Famine in Ireland: bioarchaeological contextualisation of non-adult mortality rates in the Kilkenny Union Workhouse, 1846–1851

Over half of all victims of the Great Irish Famine (1845–1852) were children. Many of these deaths took place in the union workhouses: institutions of government poor relief which for many were the last resort in a desperate struggle to survive famine-induced conditions such as starvation and infectious disease. Archaeological excavations of a mass burial ground dating to 1847–1851 at the former workhouse in Kilkenny City have provided the opportunity to undertake a detailed interdisciplinary exploration of non-adult mortality in an Irish workhouse during the height of the Famine.

A Neolithic and Bronze Age Monument Complex and its Early Medieval Reuse: Excavations at Netherfield Farm, South Petherton, Somerset, 2006

An early Neolithic causewayed enclosure, a middle Neolithic long enclosure and an earlier Bronze Age open enclosure were among a group of prehistoric features discovered and examined by excavation at Netherfield Farm, South Petherton during archaeological mitigation work ahead of the construction of a natural gas pipeline between Ilchester and Barrington, Somerset, in 2006. Of particular interest were burnt deposits within the long enclosure ditches and a possible Bronze Age field system. Assemblages of pottery and flintwork contribute to the understanding of these features and a programme of radiocarbon dating has amplified the chronology of activity on the site. Evidence from a group of burnt and unburnt pits and a partial enclosure reveal the reuse of the site between the fifth and eighth centuries AD.

Ossification of the Ligamentum Flavum in a Nineteenth-Century Skeletal Population Sample from Ireland: Using Bioarchaeology to Reveal a Neglected Spine Pathology

Ossification of the ligamentum flavum of the spine (OLF) is rarely reported in individuals of European ancestry. It has, however, been observed in archaeological skeletons from Europe. The aim of this study was to revisit OLF rates, utilising a mid-nineteenth-century skeletal sample from Ireland. The hypothesis was that the OLF prevalence rate was similar to studies on non-Europeans. Spines from 345 individuals were analysed, and the extent of OLF recorded on the cranial and caudal attachment sites of each vertebra using the following classification system: Grade 0 (no change); Grade 1 (<2 mm); Grade 2 (2–4 mm); Grade 3 (≥4 mm). OLF was observed at prevalence rates of 83.6%. There was no disparity in prevalence based on sex, except for individuals aged 36–45 years at death in which the male rate was higher. Advancing age was a determining factor in the OLF occurrence with an onset in young adulthood (18–25 years), and most severe grades occurring over the age of 25 years. OLF coincides with spinal osteoarthritis, spondylosis deformans and Schmorl’s nodes in both sexes, and with intervertebral osteochondrosis in females. The results of this study indicate that OLF is likely to be an understudied rather than rare condition in European populations.

Dental markers of poverty: Biocultural deliberations on oral health of the poor in mid-nineteenth-century Ireland

Abstract Objectives Despite subsisting on a low‐cariogenic diet comprising virtually nothing more than potatoes and dairy products, poor oral health affected the quality of life for the poor of nineteenth‐century Ireland. This study investigates potential biocultural reasons that may explain why this was the case. Material and Methods A total of 6,860 teeth and 9,889 alveoli from 363 permanent dentitions from the skeletal remains of impoverished adult Irish males and females who died between 1847 and 1851 in the Kilkenny Union Workhouse were examined for evidence of dental caries, periodontal disease and ante‐mortem tooth loss. Caries rates were quantified and assessed by crude prevalence, frequencies, corrected caries rates and a t‐health index, and evaluated by sex and age groups. Results A higher rate of caries was present among 18–25‐year‐old males than females, while the opposite relationship was evident for older age groups. The prevalence rates of periodontal disease and ante‐mortem tooth loss increased with age. When assessed by corrected caries rates, tooth decay is observed at a lower rate compared to contemporaneous lower to upper‐class population samples from London. Discussion Despite being low cariogenic foods, the potato starch and milk lactose of a nineteenth‐century Irish laborers diet would have lowered oral pH‐values thereby increasing the risk of bacterial fermentation in dental plaque resulting in caries. Nutritional features alone cannot explain the high rates of dental caries observed in the Kilkenny workhouse population sample, however, and lifestyle factors, particularly habitual clay‐pipe smoking, is considered a significant cause of poor oral health.
