In the last few days I have been looking at abstracts / e-copies of Death Certificates on Ancestry and FamilySearch primarily. While I have not obtained any originals or photos of any yet I have seen great variation in the information on them and a great source of information for the information on the deceased parents if the information is available, especially in the comments section, if present.
My question, taking into account that certificates vary by state and time period:
Is there a general guide for interpreting them and the abbreviations they may have in the comments sections?
For example in IL from the 1920s on one I found "11d at place DTH" . Ref: FHL FILM NUMBER: 1818999, Death certificates for the state of Illinois, 1916-1945, excluding Chicago with the exception of stillbirths; index, 1916-1938; internet index, 1916-1950. The rest of the family is known to have survived and they were buried 2 days after their death. I thought maybe there was a school fire (this is from a child) and searched Google and the County Historical Societies website which even has a 'Disasters" section and nothing was mentioned. But this is just an example of why I want to know how to interpret them...
My question: I am looking for a reference guide I may use to interpret these type of comments and was wondering if anyone has come across any other guides like they have for other record types mentioned in the forum?
