You are certainly correct about the Parl Fry profile. I can’t really believe I put a date like 1 January 1963 on the profile (I must have copy-pasted without giving it any thought). The fact that the “lack of sources” tag is still on the profile means I put no real work into finding sources and fixing the profile yet – it is on the To Do list.
But I would say look at the other errors on the report you linked. FAG says Parl Fry was born in Siam, Taylor County, Indiana – this is wrong as he was born in Polk, Taylor County, Indiana as proven by his birth certificate.
The gravestone of Angela Cochoit actually says she was born in 1872 – this is wrong, she was born 8 March 1871.
FAG says Hortense Cochoit was born in 1827 – this is wrong, she was born 11 July 1826.
FAG says Hippolite Manier was born 14 July 1809 – this is wrong, he was born 16 July 1809.
FAG says Hippolite Manier was born in Deuxville, France – this is wrong, all we know is he was born in France, possibly in Foug, Meurthe-et-Moselle, Lorraine, France.
Db_errors is reporting the error FindAGrave - Link without matching Grave for Clair Freiburger – this is wrong, the link works perfectly.
So, 1 out of 6 errors was correct and useful. I had to re-research every profile to figure this out. The one that was correct, almost certainly did not actually use the grave as the source of information, but derived from other sources (i.e. his death certificate on ancestry.com).
The problem with these new errors is the False Error rate, and the amount of time it takes to figure this out. The majority of the errors currently presented by the Database Error report has a very high ratio of True Errors to False Errors. Nearly 100% of the dating errors are in fact True Errors. Well over 95% of the gender errors were in fact True Errors. Over 99% of the spelling errors are True Errors. Over 99% of the relationship errors are True Errors.
The new FAG errors reverse this so that there are more False Errors than True Errors. I’ll say it again: Given the vast amount of un-sourced data on Find A Grave, and given the majority of dates and place names do not come from gravestones but from personal (inaccurate) trees. We should not be comparing the actual data in wikitree to the data in FAG and expecting them to match. It is going to take an enormous effort to check all of these errors, and it is just not worth it when so many errors are turning out to be false.
