5 rulers, 5 with terms dated as terms, covering 220 – 266. Only 46 years of the line are dated - too short for a median. 1 of 4 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”.
