How to Verify the Death of a Soul

In addition to being a Catholic apologist I'm also a parapsychological researcher. It would be very interesting to check records and see if it's possible to verify that the souls you're helping are those of people who you know really lived and who really died in the ways indicated. You indicated earlier that you haven't been called to do that kind of investigation at least yet. Have there ever been cases where a piece of information that you did not previously know popped out in a session that later turned out to be true? There have been a few others, yes.
