Lorenz proposes that the entire kinship system was not based on classes, castes, or clans, but rather degrees of genealogical separation from the ruling Sun matriline. Lorenz's interpretation does not include asymmetrical descent or noble exogamy. Rather, a person was a Sun if he or she was within three degrees of matrilateral separation from the ruling matriline's eldest female Sun (called the "White Woman"). Nobles were those people who were four, five, or six degrees removed from the White Woman, while people seven degrees or more removed were commoners. In this system, the male children of male ruling Suns would naturally descend one "class" per generation, and would be required to marry outside the "class" to avoid incest. The only exception was the case of a male child of a male Noble, who acquired the Honored title by birth.
