A death or burial certificate contains the name and surname of the deceased and date of death and/or burial. The age is almost always given. In the case of children, the name of the parents is given. In adults, the name of the partner is given. Sometimes the exact time of death or cause of death is also given. Some parish priests noted in the deed whether funeral expenses had been paid or not.
When looking up, always remember the different variations in the spelling of surnames. Also bear in mind that in some parishes the registers have been lost or have not yet been completely transferred to the database.
