Quote from jem:
factcheck is about as non partisan as hannity and who cares what they say. I agree birth announcements in a newspaper would be some evidence of a birth day.... a little less solid as to place of birth --- depending on what type of requirements the paper had for publishing birth announcements.
1. For instance if they had a photographer at the hospital and took pictures of every baby... I would call that solid.
2. If grandparents could phone it in... less solid.
They changed how that is handled a few years ago. Now the birth notices are given to the paper by the health department and they no longer print announcements by family.
