Most of the people in the database only have a name and a reference of who their father is. The database supports much more than that however.
The database holds the person's titles (Fiqi, Suldaan, Ugaas, etc), their name, their nickname (if any), any additional differentiating titles (like al-Jeberti, al-Hashemi, al-Aqeeli) and room for a biography of the person in question. Also, who their mother is.
It also holds the birth year, where they were born, the year they died, and where they are buried.
