[Dan Day]

The lineage quibble is a red herring. "Son of" was sometimes a shorthand locution for "grandson" ("great grandson" etc.) in many cases.

None of the examples I listed is resolved even by accepting "son of" in a broad sense of "descendant of".

Look at them again -- some of the lineages list A as the father of B *and* B as the father of A.

And a nephew is not a son nor vice versa, and the contradiction is not resolved even with son=descendant.

All I can say is God rebuke your quibbles. Sometimes the same name reappeared in a line.
