If you understood the definition of hearsay then you wouldn’t had made the earlier ridiculous comment about contemporaneous newspaper records, especially when they don’t list a place of birth.
And, if as you say, the notices provide no information concerning location of birth, you should even assert an objection based on relevance.
So, your point is well taken. I'm not sure if a judge would admit those notices.
I think the more important problem, though, is proving that Obama was born somewhere outside the United States without any witnesses to that fact.
