Scripts can always be customized, but it is not always easy. What you want, I think, are
1. Burial event with address (which is commonly the cemetery address) for each descendant.
2. Details on spouses, including their burial information (and note the spouses are not descendants)
I have posted new versions of the "Descendants Generations" reports (one in "Reports" folder, one in "Reports to Pages" folder and one in "Report to Word" folder) that make these customizations much easier.
1. The previous report made it easy to add extra events, such as burial, but that addition did not include an address. That process now has an option to add address for each extra event added to the report.
2. The default report has spouse names but no other spouse details. The new report scripts now have comments on how to add spouse details, which can include whatever you want (e.g., birth date and place, death date and place, parents, burial, or any other event).
The new versions are available on
http://www.geditcom.com or while running GEDitCOM II by using the Utilitles->Download Script option in the scripts menu. These scripts require the latest version of GEDitCOM II.
