Regarding mistakes - one of my relative's death cert is intentionally
incorrect. His son completed it and did not want to emphasize the fact that
his father had been illegitimate. So the father of the deceased "John Doe"
was listed as "John Doe, Senior." Had I not known the truth, I would be
wwaaaayyyy down the garden path looking for "John Doe, Sr" instead of "Tom
Smith" who was the real father.
