Choose a starting point

Search Indexed Records finds books, articles, archival collections, and digitized materials. Historical records has separate searches for deed abstracts and records naming enslaved people.

For background on a person, place, institution, or subject, its page brings together a summary, chronology entries, related works, and research sources. The chronology can help narrow a question to a date or identify events worth investigating. Orange County Indexed is a growing resource. Coverage is incomplete, and entries and connections are actively corrected and improved as sources are added, evidence is checked, and readers suggest changes. For a reference answer, follow the citation to the underlying source and check it directly.

Find names and historical spellings

Person and place pages can reveal names used in older sources: Hillsboro, the Orange Hotel, a former business name, or another spelling of a surname.

The names index lists people mentioned in the chronology, including those without a researched profile. It also notes variant names and possible namesakes. Place pages and the places index offer similar routes into older place names.

Use the search controls

In Search Indexed Records, each significant search word must appear somewhere in the indexed record: its title, author, description, notes, or subject headings. A short search followed by filters can be useful when a longer query finds nothing.

The chronology opens with selected highlights, but searches and filters cover the full chronology. Person pages link directly to that person’s dated events.

The deed and enslaved-people searches have their own matching rules and browsing options. The tour explains these differences; the no-results guide suggests other searches to try.

Open and compare the cited sources

Chronology entries name their sources and link to them where possible. These links make it easier to compare an OCI summary with the cited newspaper, history, or record.

Deed pages link from Mark Chilton’s abstracts to page images at the Register of Deeds. The abstracts can help locate a record; the original page may contain details the abstract leaves out.

The methods page explains how chronology entries are prepared and reviewed. Evaluate what you find offers questions for comparing sources and recording uncertainty.

Find materials beyond OCI

Research sources on detail pages link to relevant archives, catalogs, maps, newspapers, and local organizations. Search further on person pages provides prepared searches in other collections; those results may include namesakes.

Local history at OCPL includes a room plan and book lists arranged by shelf. For materials held elsewhere, follow the holding institution’s link or check whether interlibrary loan is available.

Working with sensitive records

Records concerning enslavement, violence, illness, and family matters may contain offensive language or distressing information. OCI’s summaries and transcriptions provide routes to the sources, whose wording and context may need closer examination.

Names preserved in a record can be valuable clues, but a shared name alone does not establish that two records describe the same person.

Save searches and next steps

Copy link to these results saves a search that can be reopened or shared. Detail pages provide links and citations, and download options support further work with results.

The research guides can be printed and shared with patrons. Worked examples cover houses, families, schools, newspapers, cemeteries, and other local history questions.

Errors or missing sources can be reported through Suggest a correction or a source.
