Grok does 7-10 years of genealogy research in 3 hours, cracking a Holocaust family mystery

An Israeli user asked Grok to find his mother's cousin, long believed to have perished in the Holocaust. Grok confirmed with three sources that he died in Auschwitz, then went far beyond: mining Yad Vashem, German Jewish archives, Polish and Hungarian archives, birth and marriage records, 1943 train transport manifests, refugee ship passenger lists, and years of scattered Facebook group comments.
Cross-referencing sources no human could combine — Facebook threads against 1943 railway records — it rebuilt the entire family tree and verified old photos. The author estimates three hours of Grok's work equals 7-10 years of human effort, and urges others to use it for family history searches while grandparents are still alive.
