3 rulers, 3 with terms dated as terms, covering 407 – 431. Only 24 years of the line are dated - too short for a median. 0 of 2 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
