That is of course true. And anything else until you actually see the piece of paper they filed on August 8, 1961 is just speculation.
That said, I have assumed that whoever did the filing would have tried for some level of credibility. Home birth. Or a friendly doctor at one of the local hospitals who might have slipped an affidavit into his regular filings. If I had done it, it would have had a footprint. But I would have been concerned if I were doing it that someone would ask to see the baby. I think that is why they waited until August 8 to file--to get the baby back to Honolulu.
On the other hand, if the filing had a high level of credibility, likely they would have shown it to you--you can suspect that looking at their filing, it will be clear how the birth in Kenya relates to whatever they say on paper.
I’m betting that Grandma did the filing with help from people she encountered at the “White Bank”, she was practical and often the buffer between the domineering Stanley and the flighty Ann as mentioned by her friends on Mercer Island and she continued this practice after Ann married Lolo as evidenced with this quote:
(Toot, forever practical, telephoned the State Department to check on Indonesia’s stability and insisted on packing trunks of food. “You never know what these people will eat,” she said.)

Farther down in the same article it mentions the one visit By Sr. and mentions a telling event:
“The worst moment of the visit came one evening at Stanley and Madelyn’s apartment. Barry had been waiting all year for the annual broadcast of “How the Grinch Stole Christmas,” but Senior chose this moment to assert paternal authority for the first (and apparently last) time. Ordering his son to turn off the TV and to go read, Senior provoked a family-wide crisis, forcing deep-seated resentments to the surface. As the argument wore on, Barry managed to see the last bit of the holiday special, but he was ready for the father to go: “After a week of my father in the flesh, I had decided that I preferred his more distant image, an image I could alter on a whim—or ignore when convenient. If my father hadn’t exactly disappointed me, he remained something unknown, something volatile and vaguely threatening.”
I believe those “deep-seated resentments” began when Ann came home to announce she was pregnant and festered through the 10 years. After-all by Sr’s own admission he was a “serial polygamist” but with one woman at a time and none of his friends and fellow students(with the exception of Rep. Neil Abercrombie D-HI) even remembers Ann. He was busy with his life, friends, and studies not even taking Ann to any of the gatherings as evidenced by the photos Fred posted! To avoid the humiliation Ann left Hawaii and didn’t return until Sr. left, having her practical mother file the record of birth.
