I'm another appalled at Find-a-Grave being considered source information without supporting evidence; given its mis-use by over enthusiastic amateurs.
I could write screeds about the errors, therein, but three in particular are frustrating beyond belief.
Some idiot (and there is no other word in my vocabulary I feel I can use) has entered an entire parish register of *BAPTISMS* into find-a-grave. I've complained endlessly, to no avail, to have them removed. 95% of the people baptised in said village did not die in said village!
Another distant family member has *memorialised* my ancestress in a cemetery for which there are *NO KNOWN* existing records. I know the history inside out of the cemetery... (and why there are no records) and although there is a possibility that's where she is buried, to state so, is just wrong.
The third was resolved, however, but this is the ultimate problem with linking to find-a-grave supposed relationships. Someone decided, that the son mentioned on my gt.grandmother's first husband's memorial inscription, was her son. This was a complicated scenario of two wives, two *sons* (by surname) and the same Christian name, but the second (the one *not* named) was born to my gt. grandmother to another man many years' after the first; whom she probably didn't even know. Including biographies from some half-sourced facts, of non-relatives; (like the instance of the aforementioned baptism register) is a problem with find-a-grave which has no means, overall, of mitigation if wrong.
