Last name origins & meanings:

  1. Korean (Ch’a): there is only one Chinese character for the Ch’a surname, and the Y{ou}nan Ch’a clan is the only clan. Their founding ancestor was Ch’a Hyoj{ou}n, son of Yu Ch’a-tal (10th century ad). Ch’a is a fairly common surname throughout the Korean peninsula, but most of the clan’s members live in Ky{ou}ngsang province, Hwanghae province, or P’y{ou}ngan province.
  2. Chinese: variant of Zha.
