Have you considered allowing people to import a Personal Ancenstory File from a geneology program to populate the people section? Although there is some around merging data this tool could be a revolution for geneology research since you are commited to open source documentation.
I have linked over 10,000 names in may family tree many including birth, death, marrige location, etc.
If you import a feature like this you may consider excluding some details on records that don't include a death date to protect personal privacy but I think this would tie into a great application.
