1 rulers, 1 with terms dated as terms, covering 1836 – 1840. Only 4 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”.

What led to it, and what came of it
The investigation's own picture: 0 causes the record names and 1 result, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
