Hey Pa mom.
I do know that foreign certificates could be filed in Hawaii at the time of Obama’s birth...that would make sense with the announcement.
But not so quickly. The announcement was printed within 9 or so days of his birth, and given the lead time with printing and the gathering of the info from hospitals, it seems very unlikely.
Also, if you read the information provided by the woman who found the announcements and researched them, the information came directly from hospitals, not alternate sources of birth.
