Every dead person has to have an obituary.
If you are dead, you must be in the Social Security Death Index.
They have always charged to put obituaries in every newspaper.
Delayed birth records were for out-of-wedlock births.
These are just a few examples of incorrect statements I’ve encountered online. One can find just about anything on some message boards, Facebook groups, etc. Before sharing or reposting advice you found posted by someone you don’t know, check it out.
And definitely check it out before you use it to reach any sort of research conclusion. “Brick walls” can result from following off-the-wall advice.
