Discussion of Dietrich Y-DNA test results

See also Dietrich DNA for a tabulation of Dietrich Y-DNA test results.

"Dietrich" was a very popular personal name in German speaking regons in the Middle Ages, and its frequent use as a patronymic subsequently led to its adoption as a surname by a large number of unrelated families when family names became widespread some 700-800 years ago. The distribution of Dietrich Y-DNA results among the broad haplogroups A-T appears to be consistent with the distribution of modern German males: R1b (M269) 41%, I 22%, R1a 15%,, and about 5% each for groups E, G and J (Y-DNA haplogroups in populations of Europe, Wikipedia article). The 1890 distribution of surname Dietrich in Germany was concentrated in Saxony and the southwest, with relatively few numbers in the northern plains.

The Genetic Familes identified by the Dietz-Dietrich Project are generally tight clusters, with members having no more than four discepancies (GD≤4) for comparisons at Y-37, implying a common male ancestor within the last 400 years or so. Moreover, these famiies are generally well separated from each other, with GDs between families generally 20 and much more. Indeed, the broad haplogroups A-T separated about 50,000 years ago and major subclades over 25,000 years ago (as shown in this chart), so the only interesting relationships are beteen familes that fall into the same subclade such as R-M269 in particular.

In this dicussion, it is assumed that all male-line relatives of a Y-DNA test taker fall into his genetic family, provided the paper trail (family tree) is reasonably secure. Thus, they will be assigned that genetic family (and haplogrop) without additional explanation. GDs are for comparisons of Y-37 tests, unless otherwise stated.


The number of unrelated Dietrich families is unknown, but is bound to be quite large since many family names were derived from personal names, and Dietrich was very popular in the late middle ages (circa 13th century) when family names were widely adopted in Europe. The table below is based on comparisons in the FTDNA Dietz-Dietrich project, with family name "Dietrich" unless otherwise noted. There are nine identified Dietrich genetic families, plus 16 unmatched individuals, which implies at least 25 different origins for the Dietrich family name.

Haplogroup E1b1b1 (M35)

E-M35 Genetic Family A. E-M35 is relatively uncommon in Europe, comprising about 5% of all Western European males, so it is surprising that three individuals from apparently unrelated families report almost identical haplotypes, classified as a single genetic family by FTDNA. Moreover, two families migrated to America about 1750 and the third to Hungary before 1793..

Johann Adam Dietrich b abt 1710 Fénétrange, Bas-Rhin, Alsace, migrated to America in 1751 with his wife and several cjildren. His youngest child Johannes Dietrich was b abt 1754 and christened 1768 Berks PA. Georg Hans Dietrich was (probably) b 1728 Durstel (17 km from Fénétrange), migrated to America in 1752 and settled in Lancaster PA where he married and had a number of chidren. Elisha Teeters b 1762 PA (possbly his son) settled abt 1785 Wahington PA. Male descendants of both families have closely matching Y-DNA.

Remarkable is the close affinity of these two familes to Johann Dietrich (abt 1769-bef 1833) who migrated before 1793 from the Rhineland (Alsace or Pfalz) to Hungary, then before 1819 to South Russia.

E-M35 Unclassified. Origins of Peter Dietrich b abt 1749 are uncertain, but he married 1779 MD and settled in wentern VA, then relocated abt 1817 Harrison IN. Unrelated to Family A (GD=6 for Y-12)

Haplogroup G (M201)

G-M201 Genetic Family A. Andreas Ludwig Dietz b 1708 Bas-Rhin, Alsace; son John Joachim Dietz Sr b abt 1757 evidently migrated bef 1776 America. No WikiTree profiles.

G-M201 Unclassified. Hans Jerg Dieter b 1699 Schwaigern, Württemberg, migr 1727 America, settled first in PA, later in VA; Hans Jerg Dieter b 1703 Schwaigern (probably a cousin), migr 1729 and settled in VA.

Henry Samuel Teter (Dieter?) Jr. b abt 1756 origins uncertain; may have been a deserter from the British army during the American Revolution; settled afterwards in Green PA. Unrelated to Schwaigern Dieters (GD=19 for Y-37).

Haplogroup R1a (M198, M512)

R1a Genetic Family A. Elias Dieterich (1701-1759) migr 1744 America from Ottmarsheim, Württemberg in the Neckar valley. Three descendants have closely matching Y-DNA test results. Ignatius Dietrich (1812-1884) born Oos, Baden on the Rhine, just 100 km to the west. There is no paper trail linking the two families.

Haplogroup R1b (M269)

Haplogroup R1b is very common in Western Europe (particularly in the British Isles) where it is dominated by subclade M269. Approximately 50% of male Germans, including Austrians and Swiss, belong to this subclade. The Dietz-Dietrich project has identified seven Genetic Families (A-G) in subclase M269, several originating in the Rhineland and one (Family E) in Switzerland. Genetic distance (GD) between these families are generally 18-32 (45-80 generations, or 1,350-2,400 years), except for families E and F where GD=11 (28 generations or 850 years).

R-M269 Genetic Family B. Members of this family migrated both east fo Galicia(?) and west to America in the 18th century. Friedrich Daniel Dietrich b 1828 Landestreu, Galicia, Austria, was a grandson of Johann Michael Dietrich b 1765 Hirschfeld (Hunsrueck), Pfalz. Another member of this family Christopher Dietrich (aka Tederick b abt 1744) migrated 1765 PA and later settled in VA. His European origins are uncertain.

R-M269 Genetic Family D. Conradt Teeter (Dieter?) b abt 1723, married 1742 and settled in Bucks PA; father Henry DIeter(?) probably came to America before 1727 but origins in Europe unknown. Three descendants with almost identical results (Y-67 and Y-111).

R-M269 Genetic Family E. Johannes "Hannes" Dieterich (b abt 1720) migr abt 1738 PA, settled 1752 Frederick MD; sons John Deeter b abt 1745 and Abraham Teeter b abt 1748 have closely matching Y-DNA (GD≤3), based on test results from at least four descendants. Very close match (GD=0 for one comparison) with a descendant of Ulrich Dietrich b 1665 Därligen, Bern, Switzerland, but paper trail linking the two branches of this genetic familly is lacking.

R-M269 Genetic Family F. Family name Dedrick/Dederick pre-1850 is largely restricted to descendants of the 1710 New York migrants Christian Diederich b abt 1660 Niederbieber, and Johann Wilhelm Dietrich b abt 1660 Segendorff. The towns are about 1 km apart just north of Neuwied on the Rhine, so they are believed to be closely related, possibly brothers. Abraham Dedrick b abt 1814 NY is a possible descendant of one of them, but no paper trail has been reported. A Living Dedrick with unreported ancestry has a test result GD=5 (Y-67) from Abraham.
