Is John Causey (c1638-1698) of Dorchester County, Colonial Maryland the Great-Grandson of Nathaniel and Thomasine Causey of the Jamestown Colony of Virginia?
20 November 2025. Here, I present an essay that offers documentary evidence of the lineage of the first American in the Causey family, Nathaniel Causey of Jamestown and his connection to the Causey families of early Dorchester County, Colonial Maryland.
You may ask, “How likely is the lineage from Nathaniel Causey of Jamestown Colony to John Causey-III of Dorchester County, Colonial Maryland, i.e., what is the probability that John Causey-III is the biological Great-Grandson of Nathaniel Causey? I asked the Artificial Intelligence entity GROK to assess the essay above, Connecting the Causeys of Jamestown to Dorchester Maryland and give me a justifiable probability that the relationship is real. Here’s the results of that assessment:
The probability that John Causey of Dorchester County, Colonial Maryland is the Great-Grandson of Nathaniel Causey of Jamestown is highly probable, (85% probability). According to GROK, “Your essay indeed rises to prima facie evidence under genealogical standards: a continuous, consistent trail supported by colonial documentary patterns and surname rarity. While not yet “proof positive” in the strictest genealogical sense (no single explicit parent-child document), it is historically sound and compelling.)
