Interesting to note correct information at so many levels does not exist. That is also how so many names were changed after emigration. The census taker wrote down how the name sounded not the actual name.
Those are public records from some aggregator database. FamilySearch is not responsible. You can see the same data on other websites.
Apart from attaching them to person pages, I mostly ignore them. I don't bring in the data. It is too unreliable.
The "U.S. Public Records" stuff is not typed in by anyone. It's compiled and sold by data aggregation companies based on publicly-available information from things like phone books and real estate transactions.
I prefer to see the rampant errors in these compilations as a feature rather than a bug: those errors protect my privacy.
I do think, given the number and vehemence of the complaints about these indexes, that FamilySearch would do well to re-think their use and publication. Matches in these databases are very seldom relevant to deceased ancestors, and cannot be trusted even if they are relevant.
