This article reflects on the 2024 public humanities project “Susannah Darwin at The Mount: Hidden Maternal Histories,” held at Charles Darwin’s family home in Shrewsbury, England. Focusing on Katy Alston’s Mapping Susannah Darwin, a co-produced creative map stemming from the project that shows The Mount from the perspective of Darwin’s mother, Susannah, I reframe the fixed project “output” as the product of much more fluid sets of relationships and circumstances. This article blends personal reflection with insights from critical cartography, concepts of the object “life cycle,” and my underpinning research on the Darwin family and home. I aim to provide an accessible but critically informed account of the practices, relationships, serendipities, and setbacks that can characterise the humanities in action.
