The Demuth family tree — a German–American line rooted in St. Louis, with branches
reaching back to 1650s Lower Saxony, the Baden village of Kappelrodeck, southern Illinois and Indiana, and
18th-century Ireland and Scotland. Click any person to see details or make them the center of the chart —

Where the family came from
Every geocoded birthplace in the tree. Migration view draws a line from each parent’s
birthplace to their child’s — the pile-up on St. Louis is four immigrant streams converging.
Deep ancestry — the two DNA lines
Beyond the paper trail, two pieces of DNA trace single unbroken lines for tens of thousands
of years: the Y chromosome (father→father→…) and mitochondrial DNA
(mother→mother→…). Each carries a "haplogroup" — a branch of the human tree. Switch the
map above to Deep ancestry (DNA) to see the schematic migration behind each. Read from a 23andMe
genotyping test.
Paternal line · Y‑DNA
I1 (I‑M253)
One of the oldest European lineages — Ice‑Age hunter‑gatherers, then a Bronze‑Age
explosion from southern Scandinavia. Common today in Scandinavia, Denmark, the Netherlands and northern
Germany.
Follows the Demuth surname to Anton Demuth (b. 1769) of Kappelrodeck,
Baden — five generations there before the line emigrated to St. Louis.
Maternal line · mtDNA
I1b
An uncommon European maternal lineage (~2%), rooted in the Near East ~30,000 years ago and in Europe
before the last Ice Age. Never common; thinly spread across Europe and West Asia.
