A close examination of the birth certificates issued by Kapi'olani to the Nordyke twins shows the registration number precedes the number given Obama, even though the future president was born a day earlier.
Susan Nordyke was born at 2:12 p.m. Hawaii time and was given No. 151 – 61 – 10637, which was filed with the Hawaii registrar Aug. 11, 1961.
Gretchen Nordyke followed at 2:17 p.m. and was given No. 151 – 61 – 10638, which was also filed with the Hawaii registrar Aug. 11, 1961.
According to a version of Obama's purported short-form certificate available from FactCheck.org, Obama was given a higher registration number than the Nordyke twins. The online image indicates the number is No. 151 – 1961 – 10641, even though he was born Aug. 4, 1961, the day before the twins, and his birth was registered with the Hawaii registrar three days earlier, Aug. 8, 1961.
