What is "maleinos"

Maleinos was the surname of a Byzantine Greek family, first attested in the 9th century, which rose to be amongst the most important and powerful members of the Anatolian aristocracy (the dynatoi) in the 10th century, providing many senior generals to the Byzantine army. After its wealth and power became the target of Byzantine emperor Basil II (r. 976–1025), it declined, although its members are still attested in Anatolia and the Balkans throughout the 11th and 12th centuries.
