Kenka

The Kenka family was a prominent Klingon family of the 23rd century, and was descended from Klingon Nobility. 

At least some of the family members were affected by the augment virus in the 22nd century. Becoming QuchHa', these members of the Kenka family passed on their more human like traits to their descendants. 

Among the QuchHa' descendants was a male named Vlict Kenka,an Admiral in the Klingon Defense Force who led the family in the mid 2260s.

The family held the Klingon world of Hrakkour IV. When the entity Quetzalcoatl - who had visited Earth several hundred years earlier - came to Hrakkour and influenced the population of the world to adopt a more peaceful lifestyle, Kenka committed genocide against the population of Hrakkour. Among the dead were many members of the Kenka family.
