That is wonderful news.
Did you receive her death certificate yet?

Death records vary from state to state, especially the early death records. They may only have the name and death date.

As death records became more common, they "improved" - listing more background information.
Many will give parents' names, IF KNOWN by the informant, who could have been a relative OR not.
Sample information:
Name
Death date
Race
Approximate age
Birth date and place of birth
Marital status
Place of death and burial
Sometimes: Funeral home handling the burial and cemetery name
