Isotopic analysis of bone for dietary reconstruction has been routinely practised in archaeology since the 1970s (Vogel and Van der Merwe 1977) and provides a long-term average of the diet over the last 10-30 years before death (Hedges et al. 2007). Unlike bone, however, hair grows incrementally (~1cm a month for human hair), providing time series information, and offering a valuable window on diet during the final months before death (White 1993; Kutschera and Mϋller 2003; Wilson et al. 2007; see Wilson, this issue). Despite this, hair has received comparatively little attention, primarily owing to its poor preservation on archaeological sites, mummies being an exception (see Wilson, this issue). Post-medieval remains, however, present an ideal case study, often being well preserved and possessing biographical data giving additional context. This short article presents a study of incremental analysis of carbon (δ13C) and nitrogen (δ15N) isotopes from hair sampled from a 19th-century individual, 'Elizabeth Robinson' (skeleton 48, Figure 1) deriving from an assemblage from St Barnabas church, West Kensington, where 55/58 burials had name plates and recorded dates of birth and death. She lived between 1768 and 1840, and died at 72 years of age. The research forms part of a wider project on post-medieval diets (Brown 2014).
