|---|---|---|---|---|
| Nebkaure Khety II | 2140 BCE – 2130 BCE | 10 years | ending not on record |
1 rulers, 1 with terms dated as terms, covering 2140 BCE – 2130 BCE. Only 10 years of the line are dated - too short for a median. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
