4 rulers, 4 with terms dated as terms, covering 1815 – 1864. Only 49 years of the line are dated - too short for a median. 1 of 3 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”.
