Gathering information about a person's relatives from burial databases is one of the most underappreciated methods of OSINT.
First, by analyzing the people buried nearby, one can find the surnames of the closest relatives (including the mother's maiden name).
Second, by the place of ancestral burials, one can find out the hometown of a person and trace the history of his family's movements.
Thirdly, dates of birth and death of closest relatives can be added to passwords dictionaries.
