Hardly necessary. His grandmother would just have filed a "home birth" certificate, fudging the date a little. The filing of that certificate would have triggered the birth announcement, just as one filed by a hospital would. The home birth aspect would be reflected on the long form Certificate, but not on the short form Certification.
The purpose of the "little deception", to have the baby be a US citizen.
I have said all along that the mere registration of birth would generate the birth announcements which appeared in both papers and then end up getting the argument that the newspapers got their information from the Dept of Vital Statistics. What a circular argument denying that the registration of birth would be done to the Dept of Vital Stats! Grandma, as a respected employee at Bankoh, would never be questioned registering the birth of her grandson and at that time to register a birth didn’t require the numerous records which are required now ie. prenatal records, well baby checks etc. they simply required a family member or a person with knowledge of the birth to register the birth.
