In my quest to find more about my family history, I have been forced to look beyond the internet. In particular I am looking for two people that died anytime from 1910 to 1920 in Pennsylvania (possibly, it could've also been NJ). Nevertheless, I looked through PA's death indices from this time, and I manage to find two candidates. However, their first names weren't listed, so I wasn't able to confirm them, and thus, I wish to be able to find full death certificates for the people in question to at least try and verify that they are the people that I'm looking for.
I will say that I am not asking for assistance finding these people beyond a few questions that I have, and in fact I do not live near PA, I just have a family line from around Philly and Camden.
I have found a request form at phmc.pa.gov in which I can list the limited amount of information that I found from the death index. However, although that form requires certificate numbers, the death index lists only state file numbers.
What are the differences between certificate numbers and state file numbers?
How may I get a certificate number from a state file number?
Are birth certificate and death certificate numbers formatted the same?
Once again, I wouldn't like help finding these people, but rather, I would like some confusion to be cleared up, as I was not able to find much information about what I am asking.
