Orange County

Register of Deeds for Orange County, North Carolina (through December 2026), and doctoral student in Geography at UNC Chapel Hill (starting August 2026). For thirty years I have been reconstructing the cadastral landscape of this corner of the Piedmont — tracing land grants and deeds, trying to connect freedom papers, sales & other legal records of enslaved people, and indigenous geographies through the language of metes and bounds. These maps are an attempt to make that history visible.
