When you get around to designing the program,
1. Deaths: the death informant, usual residence at time of death and age at death! ('cos perceived age at death doesn't always agree with the "date of death - date of birth = " arithmetic!!)
2. Marriages: Minister's name and witnesses at marriages, and a box for thier relationshipto bride and/or groom, if known.
3. Births: Birth informant
4. Occupations
...and probably quite a few other things!
Best wishes
