Cao Ding

Cao Ding was the paternal granduncle of Cao Cao, a Chinese warlord and Emperor of the Eastern Han Dynasty.

Genetic analyses confirm that Cao Cao’s eunuch grandfather, Cao Teng, adopted his son, Cao Song (Cao Cao’s father), from within the family clan. This adoption was potentially from his younger brother, Cao Ding.

Cao Ding’s Y-DNA profile was determined by genetic analyses of a tooth obtained from his tomb.
