You’re right, inconsequential. Maybe someone edited the wikipedia?

OK, Wikipedia's not exactly the Encyclopedia Brittanica. But in this case Wikipedia is almost certainly correct, and the official biography almost certainly wrong.

The Wikepedia time line is totally internally consistent:

Born Nov. '42, Graduate HS spring '60 (age 17, almost 18), start college fall '60, meet BHO, Sr. fall '60, pregnant, Nov '60, marriage Feb '61 (Parents object, but hey she's 18, so what can you do?), Jr. born august '61.

The alternative is impossible to make sense of: Born in '42, marries BHO, Sr. at age 16(?) (where, in Hawaii? what's she doing there? when did they meet?) , then back to Seattle to finish HS, then back to (??) Hawaii, then pregnant in nov 60 and junior in aug 61.
