The Mormon church is really called the Church of Jesus Christ of Latter-day Saints (of which I'm a member). It sounds like you might be thinking of the affiliated, free genealogy site, http://www.familysearch.org. It doesn't disclose data on living persons. But you might really enjoy using it to look up your deceased ancestors. My wife loves it.
