I suspect that any of those that are actually provable and mostly accurate will lead one to find their gr-gr-granduncle who died a Catholic priest in 1925 and became a Mormon in 1973. (My one gripe with the LDS and their genealogical research: it's geared towards posthumous recruitment/conversions.)
Just kidding, with a little bit of FR humor.
As for "recruiting," even LDS doctrine holds that the individual, living or dead, can exercise his/her free agency and decline or accept the vicarious ordinances........
