1700s–Present Cemetery Research
Jan 2026 - Present • 4 mos
Conducted historical research using Sanborn Fire Insurance Maps, aerial photographs, land records, newspapers, and civic publications to trace changes in cemetery layout, land use, and surrounding urban development. Analyzed gravestones, monuments, and plot organization to interpret social hierarchy, immigrant identity, and religious denomination patterns over time. Cross-referenced archival and cartographic sources to identify gaps in documentation, record inconsistencies, and relocated graves, assessing the impact on community memory. Examined local folklore and paranormal narratives associated with the cemetery, treating them as evidence of cultural response to historical forgetting and urban change. Developed a historical narrative integrating visual, textual, and spatial sources for scholarly research and potential public history presentations. Synthesized industrial, social, and cultural history to understand how cemeteries function as landscapes of memory, identity, and collective forgetting.
