Almost all - if not all - primary sourcing is hearsay. That includes birth and death certificates. No? Then why is my brother’s name Stephan when my groggy mother clearly meant it to be Stephen?

If a great case can be drawn from a source, whatever that source is, then ka-ching! Success. But if there are a dozen records all pointing in the wrong direction, and the genealogist doesn’t take the time to make his or her case, then a myth is created and perpetuated, maybe for all time
