Dates at Native Bound Unbound
Recovering Time in the Archive
Dates are among the most deceptively simple elements in any historical record. They mark events, yet they also reflect the systems of power that determined what was written down and what was left out.
At Native Bound Unbound, the work of recording and standardizing dates is both technical and interpretive. It enables the reconstruction of lives across fragmented records while acknowledging the uneven ways that time was documented in colonial archives.
Dates are not neutral—they are acts of representation. The same date that anchors an official decree may also obscure the lived temporality of an enslaved or displaced person whose birth, movement, or death went unrecorded. Our approach balances historical accuracy with ethical transparency, creating a structure that preserves both the precision and the uncertainty of the past.
Principles of Practice
- Exact Dates
When clearly stated in a document, the date of an event—such as a baptism, sale, manumission, or correspondence—is preserved exactly as written. - Fuzzy Dates
When no exact date appears, NBU assigns what we call a fuzzy date—a controlled approximation that reflects the level of certainty. A fuzzy date may represent:- A specific year (1715)
- A month and year (March 1715)
- A range (between 1715 and 1718)
- This approach allows the database to express uncertainty without erasing it, maintaining the integrity of the historical record while supporting chronological search and visualization.
- Birthdates
Many archival sources provide only age estimates, such as “twenty-five years old, more or less.” In these cases, NBU derives an approximate birth year from the recorded age and event date. The result is stored as a fuzzy birthdate, clearly marked as an estimate unless more precise evidence emerges. - Death Dates and Burials
When a death date is not explicitly stated, the date of burial is used as a proxy, given the temporal proximity between the two. This practice ensures internal consistency and allows for accurate correlation across person records. Metadata fields distinguish between verified and inferred death dates.
Implementation
Every date recorded in the NBU database is tagged with a certainty level—exact, approximate, or inferred—allowing users to see not only the date itself but also the confidence attached to it. These tags are built into the project’s data model and will support advanced filtering in future visualizations and timeline tools.
Dates are captured during transcription and verified during translation and data review. When conflicting or ambiguous references appear across documents, NBU’s editorial team cross-checks with related entries, notes, and external historical sources to assign the most accurate representation possible.
Dates are often the most visible makers on a person page (date of a baptism, a marriage, or a captivity event). However, historial records can also complicate our understanding of the actual ages of individuals in question. A baptismal record may note that an enslaved girl is 5 years old, but ten year later, her marriage record may list her as being “18 years old, more or less.” When this siutation arises, NBU researchers try to provide the most accurate rendering on the person page.
Temporal Ethics and Representation
Colonial archives often documented time according to systems foreign to Indigenous and African-descended peoples. These records—written in Latin, Spanish, Portuguese, French, or English—translated human lives into bureaucratic time: the moment of baptism, the date of sale, the year of emancipation. By contrast, many Indigenous worldviews conceive of time as cyclical, relational, and embedded in place.
Native Bound Unbound does not attempt to reconcile these worldviews under a single temporal logic. Instead, we make the limitations of the colonial record visible, while building a structure flexible enough to accommodate diverse understandings of time and continuity.
In this way, each date becomes more than a timestamp—it is an index of power, an artifact of encounter, and a marker of memory.
A Living Chronology
Through careful tagging, cross-referencing, and visualization, dates in NBU’s database form the connective tissue that links people, places, and events across the Americas. They allow researchers to trace patterns of displacement, servitude, and resistance across regions and generations.
But they also remind us of what remains uncertain—the undocumented births, the unrecorded deaths, the long durations of captivity that defy calendrical notation.
By preserving both precision and ambiguity, Native Bound Unbound transforms chronological data into a space for reflection on how history itself is written.
