I think the BC numbers are in sequence and 0bama was born in a different location than the Nordyke twins.
The Daily Pen did some work on the order of the newspaper announcements, the BC registration numbers, and the date each birth record was registered.
0bama was probably not born in Kapiolani.
1) The local register for 0bama’s certificate is U K L Lee. That person, in June 1962, apparently registered the BC for Edith Coates, born in Wahiawa hospital (22 miles from Kapiolani)
2) Wahiawa is a small town. Wahiawa is surronded by Military bases. Wahiawa is home to the Dole pineapple Plantation.
3) 0bama Sr., per immigration records, claimed to work at the Dole plantation Aug&Sept of 1960. He also claimed to work as a dishwasher during 1960.
Just a few roads leading to Wahiawa
That's a key question. I've posted before that the BC certificates might have been pre-numbered and batches sent to the various locations authorized to use them.
Pre-numbering would give a very important control and make it more difficult for people to forge or counterfeit BCs: they'd have to use numbers already used on a legitimate BC, or use some number never issued by the state.
Whether BC forms were pre-numbered in 1961 is an important question. Someone has probably answered it.
good research bump.
