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.

As noted above on the question about LinkedIn data, we're currently looking into ways to import data in bulk generically (say from .csv) which would most likely be the first import utility.
Geneology data is definitely intriguing for Freebase -- and also a bit more complicated due to the privacy issues.
