Can you describe how you've structured your database?
What tables, fields, and relationships have you set up?
Without that information, it's pretty hard to suggest a solution.
Sorry - I wasn't sure how much was too much. Here are the basics.
Households: HHID, FullName, City
FamilyMembers: FMID, HHID, FullName
Incidents: INID, FMID, Notes
So, the xxID fields link the database: One Household <HHID> Many FamilyMembers <FMID> Many Incidents
It looks like you create a report of what you need by basing your report on the incidents table and fields of related data from the other tables.
I don't know what format your report will need to take, but it might be possible to set up summary report that does this.
