Obama Birth Certificate
I'm of the belief that his actual birth certificate indicated "father unknown" but his actually biological father was Frank Marshall Davis.
The modified copy posted indicates from the numbers attached to each line that the information was filed as unknown and someone added those prior to Obama "Davis" Releasing the "original Birth Certificate."
Unfortunately the woman from Hawaii that knew was the sole fatality in an aircraft incident off the coast of Hawaii. She survived the crash, but died before being "rescued."
