The LDS database has literally never given me anything beyond what I already knew, and of the stuff that was on there, much of it was dead wrong. It can be useful for those starting out with a tabula rasa, but only in that it can point them to what they need to research and perhaps where.
Thanks for that other one, I’m bookmarking it.
My paternal seventh great grandfather has apparently received Mormon baptism of the dead multiple times attributed to multiple locations after passing away in multiple centuries. I never saw an entry that got it right, out of at least ten. The reason for the interest would be that a branch of the family converted just prior to the Civil War and went west, ending up in Utah. Contact was maintained for at least a hundred years because a few from the Utah branch came to a family reunion in the sixties. All they needed to do was ask. It’s a little insulting to imply that his baptism in life was inadequate somehow, but he’s long gone and it’s of no effect upon him. Even if it was, they missed.
The lds library in Salt Lake is digitized and now internet searchable. You can access much reference material.
