1700s–Present Cemetery Research

Jan 2026 - Present4 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.

Conducted genealogical and historical research on Peter Derr (c. 1812) using Ancestry.com, MyHeritage, census records, land deeds, tax records, and probate materials to reconstruct his life timeline and family connections. Analyzed migration patterns between Pennsylvania, Maryland, and Indiana to evaluate competing identity candidates and assess the plausibility of relocation dates. Cross-referenced census data, marriage records, wills, and death records to resolve discrepancies and confirm individual identity across similarly named individuals. Evaluated incomplete and conflicting archival records to determine reliability, identify gaps, and avoid unsupported assumptions in lineage reconstruction. Integrated local history, geographic proximity, and regional record-keeping practices to contextualize documentary silences and missing evidence. Produced a structured research report outlining findings, unresolved questions, and next research steps for continued investigation.
