Rachel is an AHRC-WRoCAH-funded doctoral candidate at the Centre of Medieval Studies, University of York. Her research seeks to uncover the nature of sibling relationships in the later Middle Ages, focusing especially on the dynamic and intersectional nature of siblinghood. Her project's recognition that sibling dynamics are shaped by gender and social standing will also generate insights beneficial to present-day understandings of familial support networks, particularly in the criminal justice system.
