Bayesian and Genealogical  Analysis of Y‑DNA  Haplogroup T‑FTE75400

22 November 2025. Probable Devon, England, Origin of the  Causey / Cawsey Lineage (ca. 900 – 1200 CE)

I wish you all a joyful THANKSGIVING. Recently I’ve been testing the use of alternative intelligence, AI, in my research. While you must be very careful in framing what you ask for, I am becoming more comfortable in using AI as a tool in my genealogical research. One of the toughest challenges in my research into the lineage of the Causey surname has been connecting our American Causey line with our ancestors in the United Kingdom. I believe I have made some progress by utilizing GROK-5 AI. Let me know what you think once you’ve analyzed the following research paper done by GROK.
