Are these transcripts? A transcript has a form feel to it. These are compiled by a probably very disinterested clerk. Each one may be different.
Is there significant difference in the vital information?
I have asked for an 'original copy' after seeing improbable information. After spending years looking for ancestor in Switzerland, I asked for the original. Yes, I had to pay again. The original showed Germany which is what all other documents said. On the line below was Switzerland.
It is very difficult to obtain an original vital record.
If the parents and birth date is close I would accept it. Genealogy is NOT an exact science.
