Visual phasing uses the DNA of three siblings to map each chromosome segment to a specific grandparent, without testing any grandparent directly. The result is a permanent chromosome-level attribution of your DNA to each of the four people who contributed one quarter of it — a tool unavailable from any other genealogical method.
A timeline doesn’t just organize dates — it’s how genealogists catch a birth before a marriage, a person in two places at once, or two men mistaken for one.
Part Two’s headline findings reverse outright: a new largest immigration window, and a supposedly empty three-year gap that wasn’t empty at all.
A Royal Navy musician who vanished into a London workhouse while his wife and son sailed to Australia without him. No DNA test yet. Could you be connected?
Ancestry’s 2025–2026 AI rollout includes features ranging from genuinely useful (Document Transcription, Full Text Search) to engaging but limited (AI Stories) to requiring careful handling (Face Match). Understanding which tools actually advance genealogical research — and which don’t — is increasingly important for serious researchers.
Fold3 is the most comprehensive military records database available to genealogists, with over 350 million records covering American service from the Revolutionary War through modern conflicts. For Dillman researchers with ancestors in American military history, it is not optional equipment.
Yellow fever, a New Orleans bakery, and two United Fruit Company crewmen — a documented origin, but no DNA test yet. Could you be connected?
The 23andMe bankruptcy of 2025 made visible what was always true: genetic data is a company asset, not just a personal record. Understanding what testing companies actually do with your DNA — and what legal protections exist or don’t — is now essential knowledge for every genealogical DNA tester.
A published genealogy — including the DFA’s own Family Group Sheets — is a compiled source pointing toward original records, not a substitute for them.
Of the 160 Dillman family groups documented in the DFA database, 106 trace their origins to Germany — concentrated in Hesse, Baden, and the Rhineland. Tracing where they went reveals a clear pattern: New York as the gateway, Pennsylvania as a transit state, and the Midwest as the primary destination, with St. Louis the most frequently mentioned inland city of all.
