The third group of the family, the Doukai of the 11th century, was the more numerous and distinguished one, providing several generals, governors, and founding the Doukid dynasty which ruled Byzantium from 1059 to 1081. These Doukai seem to have come from Paphlagonia, and were exceedingly wealthy, possessing extensive estates in Anatolia. Again, the relationship of this group with the Doukai of the 9th and 10th centuries is unclear; the contemporary writers Michael Psellos and Nicholas Kallikles affirm such a relationship, but Zonaras openly questioned it.
