funny you ask, and I can't say for sure since I haven't done any research on his research... I am a latter-day saint, but the crazy uncle isn't... but since a bunch of geneaology gets done and recorded by other members of my faith, I would bet on the latter (no pun intended).
I have a bunch of White Indians in my tree thanks to some Mormon 9th cousins but on the whole y'all are a boon to the community. The census encoding was a godsend.
yah... if you're into genealogy... LDS folk are good allies. and they have released a TON of it online for free. I have a friend who works at ancestry.com and he tells stories of his company and the LDS church getting into bidding wars for access to records. who'd have thunk there would be "fights" to scan archives.
