Interpreting DNA Results in African Caribbean Ancestry Research

DNA testing provides results that appear precise, but their genealogical meaning depends on how those results are interpreted alongside historical records. Without this context, DNA data cannot independently establish lineage or continuity.

Historical Context

In practice, DNA results provide data that cannot be directly translated into genealogical lineage without interpretation, particularly where historical records are fragmented or incomplete.

However, these results are generated through comparison with modern reference populations and are shaped by historical processes including enslavement, migration, and population mixing.

Within this context, DNA does not operate as a standalone source of genealogical evidence.

The Research Problem

DNA results appeared to indicate connections to multiple regions within West and West Central Africa. However, this information did not establish lineage, identity, or continuity across records, creating a point at which standard interpretations of DNA data could not resolve genealogical questions.

The central question was:
What can DNA results meaningfully establish—and what lies beyond their interpretive limits—in African Caribbean ancestry research?

Evidence Considered

The research drew upon:

  • DNA ethnicity estimates
  • Information provided by testing companies
  • Historical context relating to migration and enslavement
  • Existing genealogical records

Despite the range of sources available, DNA data did not independently establish lineage, requiring interpretation alongside historical and documentary evidence.

Interpretive Framework

This work is informed by the Evidence–Context Reconstruction Framework, which distinguishes between:

  • statistical outputs (such as DNA estimates)
  • historical processes (such as migration and enslavement)
  • documentary evidence (archival records)

Within this framework, no single source is treated as definitive in isolation.

This framework is applied where statistical results must be interpreted in relation to historical context and documentary evidence.

What Could Be Established

DNA results provided indications of broad regional genetic similarity.

When interpreted within historical context, they contributed to a wider understanding of population movement and ancestral background.

However, their meaning depended on how they were situated alongside documentary evidence.

These conclusions could not be derived from DNA results alone, but emerged through structured interpretation alongside historical records.

Evidential Limits

DNA results do not identify named ancestors, specific locations of origin, or family relationships on their own.
Their interpretation is shaped by reference populations, historical migration, and alignment with documentary records.
As a result, DNA cannot independently establish lineage and must be interpreted within a broader evidential context.

Conclusion

This case shows that DNA testing produces data that requires interpretation rather than direct conclusions. Genealogical meaning emerges only when DNA results are understood within historical and documentary context, where statistical similarity does not equate to lineage.

This analysis was conducted by Paul Crooks using Evidence-Led Genealogical Reconstruction.
