"Here we surveyed a total of 5321 Y-chromosomes from 127 Asian populations, including novel Y-SNP and microsatellite data on 461 Central Asian males, to ask whether additional lineage expansions could be identified." Looks like all the lineages involve Asian males, so a more probable guess would be, say, the ruling family of the Abbasid Caliphate, which reached its greatest extent around 850.
