A study on Y-STR haplotypes in the Saxon population from Transylvania is there evidence for a German origin?

Barbarii et al 2004

Abstract
Y chromosome markers are increasingly used to investigate human population histories, being considered to be sensitive systems for detecting the population movements. In this study we present Y-STR data for Transylvanian Saxons in comparison with Y-haplotypes from Romanians and other European populations. The Transylvanian Saxons, called like that since medieval times, are representing a Romanian minority population with assumed German origin. They have settled in the Arch of Romanian Carpathian Mountains in the earliest of the 12th century. Historical and dialectal studies strongly suggest that they do not originate from Saxony, but more probably from the Mosel riversides (Rhine affluent) and also from the Eifel Mountains Valley (present territory of Luxembourg). Living protected by fortified cities in compact communities, they still represent a quite distinct population in Transylvania. Males selected for this study had all Saxon surnames and were classified by the birthplace of the paternal grandfather. The typing results reflect high Saxon population haplotype diversity. Furthermore, we present data on the haplotype sharing of the Saxon population with other European populations, especially with Germans as well as with Romanians and Transylvanian Hungarians
