The Dockstader Y-DNA Haplotype
Posted by: Charles Julian (ID *****7539) Date: May 26, 2008 at 12:46:45

I haven't seen much need for a Dockstader Y-DNA project ( on account of all European Dockstaders descend from the same individual, Johann Georg1 Dachstaeder, and any First Nations Doxtators descending from Hanyery Thohwen'karahkwen1 Doxtator will instead show a North American haplotype any mystery of descent thus being solved without much need of specifics ), but there's now enough data available to say something about Johann Georg1 Dachstaeder's Y-DNA haplotype, and the results here are actually somewhat surprising.

There are now two Dockstaders in the Sorenson DNA database who show matching Y-DNA profiles. The pedigree of one subject shows descent from John N. Dockstader (Nicholas3, George Adam2, Johann Georg1), and the pedigree of the other shows descent from John A. Dockstader (George Adam3, George Adam2, Johann Georg1). These profiles match on all shared markers that were tested ( 31 and 37 markers respectively, for which the 31 markers in common have identical values ), so the Y-DNA signature can safely be projected back to at least George Adam2 Dachstaeder of Stone Arabia ( b. about 1709 Germany, eldest son of Johann Georg1 ) and presumably also to Johann Georg1 Dachstaeder himself. The signature, with original unconverted Sorenson values, is as follows ( numbers in brackets indicate data available for only one of the two subjects ):

Whit Athey's haplogroup predictor predicts ( with "100% probability" ) that this Y-DNA signature belongs to Haplogroup I1a, which is described ( on wikipedia ) as follows:

"The [ I1a ] group displays a very clear frequency gradient, with a peak of approximately 40 percent among the populations of western Finland and more than 50 percent in the province of Satakunta, around 35 percent in southern Norway, southwestern Sweden especially on the island of Gotland, and Denmark, and rapidly decreasing frequencies toward the edges of the historically Germanic sphere of influence."

In other words, haplotype I1a is highly indicative of Scandinavian ancestry.

Needless to say, this finding doesn't support my earlier analysis of the surname Dachstaeder as denoting someone originally from Dachstadt in Bavaria ( southern Germany ). Instead it suggests "Dachstadt" may be a Germanized variant of a Scandinavian placename Daugstad / Dukstad / Dogstad / Dagstad, where the final element -stad is cognate with German Stadt and means "town" or "village", and the first element might mean anything from "Duke" to "Windlass" to "Dagr" ( a name ), all depending on the place.

If this is indeed the case it might also explain why the Dachstaeder surname was often recorded as "Dogsted" or "Dachstaed" in early New York Palatine church records: the suffix -er ( meaning "[male] person from" ) may be a German addition that was not originally part of the name. An added bonus here is that while the name "Dachstaeder" is unheard of in modern Germany, the Scandinavian surname "Daugstad" and its variants are actually not that uncommon. If Y-DNA has a further part to play in Dockstader research it may be to see whether Johann Georg1 is related to any Daugstad, Dukstad ( etc. ) families still living in Scandinavia or Germany.
